We were quite excited moving to Firefox 3, but with the move many of the extensions stopped working all together. One of the extensions that stopped working for us was Greasemonkey, for which luckily we found a alternative some time back.
Few other extensions like Google Toolbar and Google Browser Sync which we used to sync up our bookmarks, tabs and history across computers had also stopped working. We expected Google to release a update soon but learnt today that the Google Browser Sync extension will no longer be supported for Firefox 3.
