I've made two themes based on Firefox 2's default theme for Mac OS X that show the favicons in bookmarks toolbar. They're waiting for editor's approval on addons.mozilla.org, but I'll email to you them here if you're too anxious. PM me your email address. Mac Favicon theme Firefox 2's default theme for Mac OS X, but with favicons enabled in the bookmarks toolbar! There is a variation of my this theme called; Mac Favicon XL. Could be useful to use in conjunction with Favicon Picker (When it becomes available for Firefox 2). Mac Favicon XL Firefox 2's default theme for Mac OS X, but with Xtra Large favicon's and no text in the bookmarks toolbar! This is a variation of my other theme; Mac Favicon. Mac Favicon XL works best with favicons of 32x32px, (see image). Therefore it is powerful to use in conjunction with Favicon Picker (When it becomes available for Firefox 2). Installation instructions PM me your email address, so that I can email it to you update Firefox to Firefox 2.0 if you haven't already go Tools > Add ons in Firefox click and drag the .jar file you downloaded into the Add ons window. wait for 3 seconds click install click on the Themes tab click on the new theme click 'Use Theme' restart firefox check it out! Let me know if you have any problems with them. I've tested them both on Firefox 2.0 on Mac OS X 10.4.8.
