Maybe caused by one of the plugins as the plugin-container process seems to be involved.

I have the same problem that can be stopped by going into options and disable javascript

Between crashing, failing to work with tabs on some Ajax pages, stallling for minutes at a time, and STILL not having provided a fix for the Flash plug-in issues (something that's been a known issue since at least February!) it seems to me that Firefox is becoming virtually unusable.

I've switched to Chrome for most uses now. It's not perfect-- it doesn't handle OWA/Exchange webmail well-- so I go back to FF for that. But it also doesn't have ANY of the issues identified above.

And like others, I've done everything-- re-set, re-installed, started in safe mode, removed plug-ins, gone to the default theme-- none of it makes a difference.

I've been a loyal FF user since Beta 0.3. I grieve what has happened to it in these past several months. I'd like to be able to use it again for all functions. And I gladly would if these issues with Windows OSes were resolved.

But right now, I just can't. FF just DOESN'T work.
