Favicon Picker 2

Favicon Picker 2 adds a UI for replacing bookmark icons. This extension is based on the version posted in MozillaZine. It also features an increased icon size limit.

How to Use:
Just right-click any bookmark and select Properties, then click Browse... to select an icon or paste a URL to an icon.

Install Favicon Picker 2 for Seamonkey 21.b3+:

A user reports that:

The Favicon Picker 2 extension you posted on your site is quite buggy. The Seamonkey-compatibilized version you posted works with SM 2.1, MOSTLY... but it interferes in the normal Seamonkey process of fetching site icons. It appears to invert the normal precedence, favoring root\favicon.ico over <meta> tags. For instance, if I check the Teoma search page, the favicon I get is the one.

Fortunately, there IS a workaround (an annoying one, but better than nothing): to keep the extension disabled most of the time, enabling it only for the time needed to manually change a favicon -- this part of the extension actually works.

Flat Bookmark Editing

Flat Bookmark Editing: When managing bookmarks in SeaMonkey, if you want to change the name, link, or other information for a particular bookmark, you normally have to go through a multi-step process: select the bookmark, choose "Properties", choose the tab you want, edit a field, and finally click "OK".

The Flat Bookmark Editing streamlines this process by providing access to all the bookmark detail fields in one flat view, right inside the Bookmarks Organizer. Changing a field is now simple: select the bookmark and edit a field. Your change will be saved when you close the window or move on to another bookmark, or you can tap "Enter" to save your change immediately.

The bookmark listing is ordered alphabetically in a case-sensitive way. Filters match against bookmark name or keyword.

Usage tips

The Properties panel that this add-on puts in the Bookmarks Organizer can be temporarily hidden using the "Properties" toggle in the "View" menu.

The "up" and "down" arrow keys change the current bookmark selection, even when you're editing a field. When combined with "tab" and "shift-tab" for moving between fields, you can rapidy adjust several bookmarks without reaching for the mouse.

PlainOldFavorites is a Mozilla Firefox extension that allows you to use the Internet Explorer and Windows Favorites directly from Firefox.

Firefox has a great Bookmarks system. It has many wonderful and useful features, and the bookmarks can be exported and imported from many bookmark formats. There are even several extensions out there that allow you to synchronize your bookmarks with a remote server, the Windows Favorites folder and so on. Some users still wish to keep some or all their bookmarks in the Windows Favorites folder. There can be several reasons for this. First, some new Firefox users might find the transition to Firefox smoother if they can still use their familiar Favorites folder. Also, a link to the Favorites folder can be found in several places throughout Windows, which makes it a convenient option for storing links. PlainOldFavorites allows using the Favorites folder directly from Firefox without needing to import or synchronize the bookmarks first.

RSS Readers


NewsFox is a RSS/Atom News Reader extension for Firefox. It functions much like a typical email client - similar to Thunderbird's RSS reader. NewsFox uses the parsing engine from the Sage project.

Install the latest version from the NewsFox Project Page.

Link Status

Link Status is a Firefox extension which shows a star icon on the status bar when the mouse cursor is over a link to a bookmarked or visited page. It shows a yellow star if the page is bookmarked, and a white star if the page is visited but not bookmarked. It also shows the date you visited the page last time.

Link Status works not only for text links but also for image links, which usually lack a visual clue about whether they are linked to visited pages or not.

Link Status works in Firefox 3.5.x and Firefox 3.0.x. When using Link Status in Firefox 3.5 or later, you can choose to stop Firefox from rendering visited links differently. To do so, select the "Disable visited link styling" ("Ignore :visited link style" in Link Status 1.1) checkbox from the Options/Preferences button in the Add-ons dialog box. By doing so, you can prevent a web server from abusing this feature of Firefox to probe which pages you have visited ( Bug 147777), thus reducing the risk to privacy. Read this for the details.

Supported languages are Japanese and English (US). The English (US) version will be used in Firefox in other languages.

The icons may not be consistent with your theme. See this page for instructions of how to change them.

The latest versions of Link Status are compatible with SeaMonkey 2.0. Please install from:

For multiple links, The View and Context menus contain the menu entry to "Mark Links Un/Visited", which provides the ability to mark all links, or those within a selected region, as visited or unvisited.

If the 'Always Mark Bookmarks Visited' preference is on, bookmarked links will not be marked unvisited.

Make Link

Make Link an extension for Mozilla Firefox which adds a context menu item (Make Link) which allows the user to easily copy links to the clipboard in HTML, forum-code or simple "text (URL)" format. It also allows the user to create his or her own link types to use with the extension, and to modify or remove the default three. From version 3.0.1 there is also support for Markdown by default.

The function works in three different ways.

  • When used on a link it uses the link's own URL and link text for the new link.
  • When used on selected text it uses the page's URL as the new link URL and the selected text as the new link text.
  • When used elsewhere it uses the page's URL and title for the new link.
The copied link is stored in the clipboard to be pasted into whatever application the user wishes.

Are you always changing the text zoom level when you open a new browser window? Do you find some sites you visit have impossibly small fonts and you are constantly changing your text zoom back and forth as you visit different sites?

NoSquint is a Firefox extension that allows you to adjust the default text zoom level, which is very useful if you have a small display or run at a very high resolution. NoSquint also optionally remembers the zoom level per domain. Until website designers (typically those who know of no life outside Internet Explorer) who insist on using font-size: 50% are administered a harsh LARTing, NoSquint exists to make web browsing tolerable in FireFox SeaMonkey.

Nuke Anything Enhanced

Nuke Anything Enhanced allows hiding of almost anything via context menu 'Remove Object' or 'Remove Selection' with possibility of multiple undo of 'Remove Object'. You can also make a selection and chose "Remove everything else" to clear the page and only leave the selected text.

Once you decide what you want to Remove, Right click on it or select it, then select "Remove this Object" from the menu.

The effect of this extension is temporary, which is useful before printing a page, you can use another extension, 'Remove It Permanently' if you want your removed objects to be remembered.

If you move the mouse over "Remove this object" and wait for a second without clicking, the object that will be removed blinks in red. If this bothers you and you want to remove it, you can go to about:config search for extensions.nuke_anything_enhanced.autoblink and set the value to empty. If you want less intrusive blinking you can set it to "3px solid #ccc" or "1px dashed red" without quotes.

Resizable Form Fields

Resizeable Form Fields resizes HTML form fields, including textareas, select boxes, text fields, and iframes.

It's that time of year again: updating the essential Resizeable Textarea plugin (which seems to have been abandoned by its creator, Raik Jürgens) so that it works with the latest version of Firefox.

Jeremy Zawodny carried the torch during Firefox 1.5, and I just discovered through Asa Dotzler that John Baker has done the honors by upping the maxVersion for Firefox 2 (though it's hard to find).

There's two obvious things that the plugin doesn't do that I've always wished it did: resize select boxes and single line text boxes and iframes. So this afternoon I popped open the hood and made it happen. I'm also going to submit it to so it has a more permanent home. In the meantime, feel free to install the plugin from here by clicking on the link below.

Stylish allows easy management of user styles. User styles empower your browsing experience by letting you fix ugly sites, customize the look of your browser or mail client, or just have fun. With an online repository at, you don't even need to know how to write styles yourself; just a couple clicks and the chosen style is applied. Stylish is to CSS what Greasemonkey is to JavaScript, and unlike other methods of using user styles, most styles take effect immediately.

This extension uses the extremely popular and useful site,, to generate URLs.

Using the TinyUrl Creator

It's very simple to use the TinyUrl Creator.

Toggle Word Wrap

Toggle Word Wrap toggles word wrapping in SeaMonkey Message Composer windows and in PRE elements in the browser.

With SeaMonkey, it comes in handy when inserting long text lines which should not get wrapped in the final message (such as log file entries). It only has an effect when using plain text mode for composition - this is a per-account setting which must be configured by disabling "Composition & Addressing" -> "Composition" -> "Compose messages in HTML format".

Unchecking "Enable Word Wrap" in the Options menu (or pressing the keyboard shortcut) will temporarily turn off word wrapping for the current message - lines will take up the whole width of the composer window, and no line breaks will get added to the outgoing message (with the exception of "hard" line breaks inserted manually). Checking "Enable Word Wrap" will enable word wrapping again and set it to the width specified in the standard settings ("Wrap plain text messages at", default is 72 characters).

In the browser, checking "Enable Word Wrap for PRE Elements" in the View menu will temporarily enable word wrapping for PRE tags in the current document (by adding a CSS rule to the HEAD element). Unchecking the menu entry will revert the document to the previous state (no word wrapping). The following page can be used to see the effect, e.g.:

InspectorWidget (IW) adds a toolbar button and context menus for invoking the DOM Inspector (DOMi) for either chrome or content elements. Features include:

1. Clicking the toolbar button will enable the next mouse click on any chrome or content element to open a DOMi window with it positioned on the parent element in the respective DOM tree.

Selecting a menu will immediately bring the selected window/dialog to the front thus allowing easy and quick access to clicking the element of interest. EXCEPTION: IW (as are all toolbar buttons) is disabled when the Options dialog is open and it must be interrogated using the standard DOMi method.

3. Context-clicking the content area will present two options to allow inspection of a page and, if relevant, the inspection of an individual frame.

JSView All browsers include a "View Source" option, but none of them offer the ability to view the source code of external files. Most websites store their javascripts and style sheets in external files and then link to them within a web page's source code. Previously if you wanted to view the source code of an external javascript/css you would have to manually look through the source code to find the url and then type that into your browser.

Well now there's a much easier way. You can use the JSView extension to solve the problem. You can access it from the context menu, from the toolbar, from the view menu, or from the status bar. If the website you are viewing contains any external js/css files, an icon will appear that says "CSS", "JS", or both. Each individual file can then be viewed by clicking on the filename. The file will be opened in a new window. You can also choose to open all external files by clicking on "View All".

With the latest version you can now view the embedded css and js as well (FF2 and SM2 only). Just open the "Page Info" window from the context menu or tools menu. There will be 3 new tabs in that window. One for scripts, one for stylesheets, and one for frames. You can open them by double clicking or by using the context menu.

You can also right click on the 'view page source' menu item and open the url of the current page with jsview. This allows you to open the source code of any web page in a new tab or in an external editor.

There is a new version of JSView out but while it claims to be SeaMonkey compatible, it doesn't work after you install it. I've downloaded it and fixed several problems and corrected some coding errors. This modified version now works in SeaMonkey 2.1 and above. Install JSview 2.0.8 for Seamonkey 2.1+ and Firefox 4.0+:

JSView appears to have been abandoned by the author. It hasn't been updated since July 2008. I have taken the latest version from and updated it for SeaMonkey 2.0+ and Firefox 3.5+.

Leak Monitor

Leak Monitor pops up an alert dialog to warn chrome and extension developers about one particular type of leak. It warns when chrome windows close but leave other code pointing at their JavaScript objects.

Since the cycle collector code landed on trunk in January 2007 Leak Monitor does not give accurate nor useful results. Use the perl script in conjuction with the NSPR.log instead.

Version 0.3.0-mod has a rewritten installer to address several issues identified by dbaron. Because of this, you should uninstall any previous version before installing this one.

Version Fixed a nit reported by Neil (moved the Copy-to-clipboard button to the left of the dialog box).

Version 0.2.0 has a copy-to-clipboard button so I've removed the leak.log hack.

It looks like SeaMonkey doesn't support logging of leak events so I have patched v to save the window contents to a file within the profile directory (%Profile%/JSConsoleOutput/leak.log). Currently there is no way of turning off this logging.

Update Channel Selector

Update Channel Selector allows you to change the update channel your application receives updates from. If you don’t understand what this means then read about update channels.

Be warned, this extension will allow you to change to an unstable update source. Unless you know what you’re doing I suggest you don’t use it. If you lose all your data because you accidentally update to an unstable version then don’t come running to me.

Please note that Mozilla do not provide automatic nightly updates for users of localised builds. Until those are provided this extension can only help you switch between the beta and release channels for such builds.

To change the update channel in SeaMonkey 2.0a, Go to Edit → Perferences → Software Installation → Change Update Channel, then click on the "Select the new update channel" button.

View Formatted Source

View Formatted Source displays formatted and color-coded source and optional CSS information for each element.

You can see exactly which CSS rules match for an element. The rules are displayed including file name and line number. The topmost element is that with the highest priority.

You can fold/unfold/hilite block elements (table, tr, td, div, span,...). Really cool feature: select a block level element of interest directly in the page and view it's source! To help you to quickly analyze the source code you can view images directly from the source and add comments to folded block elements. The code view is based on the rendered document, so you will also see dynamically (by Javascript) created and modified html elements! Works also with frames and selected text.

This mod contains the following enhancements:
  • SeaMonkey compatibility.
  • Minefield 3.0a and SuiteRunner 2.0a compatibility.
  • Better method to detect Firefox version.
  • Display font changed to a monospace font for better readability.
  • [SeaMonkey Only] Added items to the menubar for File→Print; Edit→Formatted Source Options; and View→Text Zoom. You can also use the CTRL+/- keys to zoom the display text.

Tabbed Browsing

Duplicate Tab

Duplicate Tab allows you to clone a tab along with its history. So you can browse forward or backward in the history of the cloned tab, while reading the current page in the original tab. You can duplicate a tab to a new window or to the same window as the original tab.

Duplicate Tab also allows you to open a link in a new duplicated tab, so the new tab will contain the history of the original tab. Another feature is the ability to merge windows: When you have several windows open, you can merge all tabs in all windows into one window, thereby closing the other windows.

All three actions can be invoked through the tab's context menu or through shortcut-key's:

  • Accel+Shift+U to duplicate a tab to a new tab in the current window in Firefox.
  • Accel+Shift+T to duplicate a tab to a new tab in the current window in Mozilla Suite / Seamonkey.
  • Accel+Shift+N to duplicate a tab in a new window.
  • Accel+Shift+M to merge windows in Firefox.
  • Alt+Shift+N to duplicate a tab in a new window in Mozilla Suite / Seamonkey
The Accel key is the Ctrl key on PC's and Cmd on Mac.
Duplicate This Tab

Duplicate This Tab provides the much needed feature update of Tab Duplication to Mozilla Firefox and its cousins. Features Supported include Duplication of Browser Tabs, Detaching Tabs and Merging All Windows.

Whenever a need to have two or more copies of a tab (for many reasons...), detach an existing tab (and place it in a separate window) or want to merge two firefox windows, you'll find this addon to be of great use.

This add-on is a port of the popular Duplicate Tab add-on, which is no longer supported by that add-on's developer.

Load Control adds toolbar buttons that stop loading all tabs or reload all tabs in the current window.

To add the buttons to your toolbar: From the View menu, choose Toolbars, then Customize. You can drag the Stop All and/or Load All buttons to any existing toolbar. The stop and load buttons only work with the window that has focus -- so all tabs in the current window will stop loading when you click the Stop All button, and all tabs in the current window will reload when you click the Load All button.

Install Load Control 0.3 for SeaMonkey 2.0+:

Tab Clicking Options

Forecastbar Enhanced is an enhanced version of the popular Forecastfox extension ( by Jon Stritar and Richard Klien. This adds 12 improved radar images for the US, many new images for international locations and the ability to supply a URL for your own radar image. It also allows for pausing, restarting and setting the frequency of automatic weather data updates.

Please uninstall all installations of Forecastfox and Forecastbar Enhanced before installing this. If you are using ZoneAlarm firewall you will need to disable ad blocking for the animated images to work.

The Dictionary Search project is a Mozilla extension that lets you easily look up the definition of words on a Web page using an online dictionary. Simply select a word, right-click, and you'll see a menu option to define the selected word. The definitions are returned in a new window.

The Dict project is an implementation of a DICT protocol client. The DICT protocol is defined in RFC 2229. By default, the Dict extension queries the DICT server on for definitions, but it can be configured to use any DICT server.

Feature Set

The latest release of the Dict project is usable, but does not support the full set of features planned for the 1.0.0 release. The following features have been implemented:
  • A "define selection" pop-up menu item that defines the selected word.
  • When no definitions are found, a page of nearest matches is returned.
  • When only one nearest match is found, its definition is returned.
  • Can be configured to use a user-selected server. Depending on the chosen server, the extension can be used to define words in other languages and/or translate words from one language to another.
  • Rudimentary support for the "dict" URI scheme.

Install Dict for Seamonkey 2.0 and above:

CookieSwap is a Firefox/Mozilla extension that enables you to maintain numerous sets or "profiles" of cookies that you can quickly swap between while browsing.

Common uses

CookieSwap allows you to swap all your cookies out of the browser's memory and swap in a new set of cookies. This is useful for tasks like:

  • Changing your cookies/identity to web e-mail sites (like Yahoo, Gmail, Hotmail, etc) so that you can quickly look like different users. Nice if you maintain multiple accounts and are tired of logging out and then back in to switch accounts. Also nice if two people are using the same computer and want to switch between accounts quickly.
  • Changing your cookies/identity to see how sites like Amazon and Google treat you differently depending on who you are. For example, if Amazon recognizes you as a returning shopper they give you a different looking page (and there were claims that they give you different prices also). Google has begun to use a feature called "Personalized Search", where they modify their search results based on your user identity. There is a question about this when you create your Google account. The results of Google searches are different depending on if Google knows you or not. Use CookieSwap to quickly swap between Google recognizing you and being anonymous. Run the same search and see the differences.
  • If you design web sites, you can setup numerous cookie profiles to look like different types of users and swap between those users quickly and easily to test your site in numerous modes (you can hand edit the cookies to have distinct values in each profile using a nice extension like 'Add & Edit Cookies').

Install CookieSwap for Seamonkey: cookieswap-0.5.1-mod.xpi


DerBrowserTimer is a timer/clock/alarm add-on for the Mozilla FireFox browser.

It allows you to set an audible and/or visual alarm by specifying the alarm time in one of three ways: as a relative count down time (e.g. set the alarm to go off in thirty minutes), as an absolute target time (e.g. set the alarm to go off at 7:45 am), or as a regular interval (e.g. set the alarm to go off hourly at five minutes before the hour). In addition, Der Browser Timer can be set to signal the hour and/or half hour with an alternate tone like a cuckoo clock.

To reposition the DerBrowserTimer button in SeaMonkey, rightclick on the button and then select "Move Button..."

Install DerBrowserTimer for Seamonkey: derbrowsertimer-0.4-mod.xpi


Diggler is a small but powerful add-on for Firefox. It adds a menu button next to the address bar with actions relevant to the current URL. The button's menu allows you navigate up through the current URL's parents, to visit the equivalent ftp URL, or to visit the site in A single click on the menu button also easily clears the location bar (much like the one in Konqueror) - useful for keyboard free browsing. It also has a few security control tick-boxes (popups, tabbing, images) and the ability to add custom URL conversions/manipulations.

Neo Diggler is a tidy-up, bug-fix and minor re-organisation of the original Diggler by Adam Lock, which although popular has sadly been neglected and, as of it's last official release (0.9) only worked up to Firefox 1.0.*.

  • Backup reminder. FEBE can alert you if a backup has not been completed in a specified number of days.
  • Comprehensive results report with links to the author’s extension/theme homepages.

  • Verify your extension directory. Upgrading Firefox versions sometimes leaves garbage in the extensions directory. FEBE can clean it up.
  • Quick Backup. You can quickly backup as many or as few individual extensions/themes as you like. They can be saved together in a single, installable xpi file (Similar to CLEO).
  • … and more!

FlagFox is a simple extension for Mozilla Firefox that shows a little flag icon in the status bar indicating the current website's server location. It uses relatively little resources, and works by accessing an IP address database contained within the extension rather than relying on top-level-domain roots like ".com" or ".uk". Clicking on the icon brings up further information from Wikipedia or Geotool, which is an online Geolocation tool. Geotool attempts to get more information from the Website's IP address, such as ISP and city and shows the location on a Google Map.

NOTE: If you were a user of Flagfox II and are concerned about the large performance impact by this extension, thanks to the work done by Dave Garrett this is no longer an issue with version 3. The latest versions of Flagfox are now compatible with SeaMonkey 2.0. Please install Flagfox 4 from
