Does anybody else have the problem that Firefox crashes quite a lot nowadays? Also for spelling check it has become useless.

Nope - even using 3.5beta that's been 'optimized' for Vista - not a crash since I've built this new rig. I usually use 3.0.10 and that's stable as well. And the 3.5beta is faster than hell - but some of my plugins don't work for it yet (Ad Block+ being the biggy).

That's funny cause I can't log into my bank account without the bloody thing crashing and sometimes it happens if I want to watch a vid. My daughter complains about it too. She's got an account with the same bank and watches tv series regularly on the puter. We don't have these problems with IE.

Did you recently add a add-on that might be having issues with streaming video or encrypted connections? I remember I had issues on my old XP rig after I went a bit nuts adding a load of new and nifty add-ons. I had to go through them one at a time disabling them until I discovered the culprit - don't remember which it was but I seem to remember it was a add-on that was from their labs - to it wasn't really ready for primetime.

No I haven't recently added an addon. I read in the Firefox site that some addon or the other could clash with wmp. But I don't have the addon they mention. Anyway you've pointed me to the right direction. I'll disable a few media player addons which I have and see what happens.
