If you have read my post about Firefox Addons you saw that I made reference to Google Browser Sync. Google Browser Sync is a Firefox extension that continuously synchronizes your browser settings – including bookmarks, history, persistent cookies, and saved passwords – across your computers. This is very useful if you more then 1 computer, like a desktop and a laptop. What happens is that Google is no longer developing this addon, so it won’t be available for Firefox 3.
But this is not all about bad news. Mozilla is working on their own Sync Addon for Firefox, called Weave. Weave does pretty much what Google Browser Sync did. It’s still an early project so you can’t find it in their addons page. If you interested in Weave (I’m using it right now with Firefox 3) you can find it here. You need to register and after you get the chance to download it. Install it on all your computers running Firefox, login… and Voilá! :)
