Just a brain dump.

• Firefox for Solaris can be downloaded from Contributed Releases
• 3.0 (release) is actually 3.0rc2 for Solaris
• 3.0 eats less resources than 2.x
• Font anti-aliasing is broken (also, see here)
• 3.0 looks faster than 2.x
• 3.0 is EXTREMELY slow if x-forwarded (I tried to forward from a non-global zone to a global one). I heard that the reason might be Xrender lib. Related bug 6699647?
• X-forwarding crashes Nevada b92
• Most of useful extensions are not (yet?) ported to 3.0 (e.g. adblock(updated), tabmixplus (here’s a dev version), X-Ray)
• 3.0 is not included into b93 (see here)
• Field Guide to Firefox 3
• Firefox 3 Revealed - Free PDF book
• BadGC with flash in non-current tab on Solaris (This bug should be fixed in Flash Player 9.0.125.0. See announcement)
• 3.0 becomes an unkillable process if started from a zone
