After my previous experience with Firefox 3.0, you'd probably come to think that I wouldn't even bother taking Firefox 3.0 RC1 for a spin. Nonetheless, my curiosity got the best of me, so I went and downloaded the latest build from Vector64. Imagine my surprise when Minefield loaded up with Googlebar and Adblock Plus clearly functioning as they should! ChatZilla and DOM Inspector appear to be in working order once again as well.
Firefox's new theme is still terrible, except this time around I managed to force a recreation of the Firefox 2 theme onto Firefox 3 with a simple RDF tweak, as was possible in the good old days of Firefox. The theme also took care of the design issue I had with the new FTP client, returning Firefox's FTP interface to a slightly more stylized version of 2.0's flat list.
I'm glad to see that Firefox 3.0 RC1 and the simple addition of a theme were able to solve so many of the issues I had with Beta 5. I suppose that I'll be all set with Firefox until 4.0 comes out with Prism and Weave...
If anybody from Mozilla or a third-party builder is reading this, I'm still waiting for a 64-bit Lightning extension for Thunderbird.
