Install Favicon Picker 2 for Seamonkey 21.b3+:
favicon_picker_2-0.6.1.14-mod.xpi

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 Ask.com 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.

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 "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.

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.
