Firefix 3.5.5 is out from the Mozilla people—the response to yet another “annoying” buy. What do you think, gang? Is nirvana at hand or close? I have it going right now, and at least the startup was smooth. The suspense builds.
Downloads are here; release notes, here; Techmeme roundup here.
I don’t remember exactly what your issue was with the new Firefox but I was having some issues of my own not too long ago. I eventually realized that my newly installed Skype add-on was crashing the browser. Have you checked all your add-ons? This problem arose on my Vista desktop. The problem didn’t seem to exist on my XP laptop, although I didn’t leave the add-on installed for very long after the issues I had with my desktop.
