OK, so I’m amazingly fickle. But the next major version of Firefox (2.0) is currently in its third alpha stage, codenamed Bon Echo (Literally, ‘Good Repeat’ I think). It is not ready for prime time, and may not be for the faint of heart (i.e., testers and developers only at this stage). If you cannot resist taking a peek at the embryonic Firefox 2.0, I would recommend backing up your profile first, and restoring it afterwards. I did not (foolishly), and have suffered search engine icon oddities at the very least (I fear further damage to my profile, so I may have to recreate it).
