I’ve been using an early version of Firefox 3 Beta 4 for a few days (Beta 3 before that)… And while it seems like we’re making progress, I’d suggest waiting for a release candidate – unless you’re a developer or enjoy living on the bleeding edge (like me) and are prepared for the numerous crashes that come with the territory. In addition to under-the-hood tweaks and a SQLite database, the interface is being refreshed. So far, the Windows version is looking better than the Mac one. In fact, the non-graceful button aliasing is an eyesore that I’ve dumped in favor of GrApple Delicious. Speaking of living on the edge, I’ve also been playing with the Internet Explorer 8 Beta under XP – with its fair share of errors, too. (The IE7 compatibility mode is a nice feature, since you can’t install and run IE7 and IE8 concurrently.)
