I’ve had two problems with using Firefox as my primary browser on Mac OS X.  The first is speed.  The stock Firefox builds on Mac OS X are anything but fast.  The Intel- and G5-optimized builds available from a few sources are better, but they have their own issues.

The other issue I have with FF is in stock form, it’s ugly.  The form widgets and stock theme are really unattractive and don’t fit with the “look” of OS X at all.  Us Mac users (especially those with designer in us) like our stuff perty.  The form widgets in FF2, especially, are a hideous crime against humanity.

Good news… Firefox 3.0 beta 1 fixes both of these issues (especially if you install the “Proto” theme, which I’m told will be the default OS X theme upon release).   FF 3.0 is fast in beta-uno form, which is a good sign of things to come when it goes release.

I’ve been using it as my main browser for a few days now, and I’m honestly not missing Safari at all… which says a lot.  Since Firebug isn’t FF3-aware (yet), I’m still using 2.0 for development, but for day to day use I’m loving 3.0b1.
