However, for the past three months myself and other members in our staff have been forced to downgrade to older versions of FF2 or look elsewhere for a stable browser since Firefox 188.8.131.52 just kept crashing on us no matter what we did. From the response I got on a blog post back in December we were not alone either.
You can download Firefox 184.108.40.206 today (Windows/Other platforms) which according to the release notes fixes "crashes with evidence of memory corruption," so it's a recommended update for everyone. There is an even brighter future for Firefox ahead. If you haven't tried the Firefox 3 betas, I can tell you it feels speedier and more responsive, although the lack of compatible add-ons make it a big no-no for daily use at least for now. Mozilla is expected to release Beta 3 next week.
On even more related browser news, Apple is cooking some interesting features for Safari 3.1.
