At work I have a pretty good computer, but the friggin' Firefox and Opera crash many times in one hour of browsing. Now I've read that the most likely cause is the Adobe Flash Player, who's versions do not yet support native 64 bit. It's said on their website that native 64 bit version of Flash player is under development, and I think Linux users have or had the option to download a beta of the 64 bit Flash.
The problem of those crashies was so critical, that the Firefox added an additional executable to its installation, called Plugin Container, to prevent primary application from crashing. Well, from experience, I can say that that doesn't really work as well as it should, since in most cases both PluginContainer AND Firefox crash (at least for me).
NOTE: My Opera is also crashing, because the Flash plugin is shared with the Firefox.
Chrome, on the other hand, doesn't crash completely, but tends to display that the Shockwave Flash plugin crashed, leaving the main window open and active. Guess he has better handling of plugins.
Safari and IE 8 - I haven't been using them enough to see if it crashes too.
I had those same problems in Windows Vista 64bit Ultimate, and now in Windows 7 64bit Pro.
Anyone else having those problems?
Do you know of any "custom" workarounds?
