Since I installed the official win7 ultimate, FF 3.5 keeps crashing. no matter if only one or 50 tabs are open or what I'm doing, i.e. whether the window is active at the time of the crash.

any advise?

Window 7 32-bit or 64-bit?

Window 7 32-bit or 64-bit?

32-bit

what crash error message u get? or there is none?

Tried the Firefox 3.6 yet?

Im on win7 64 ultimate with FF3.5, its only ever crashed once or twice but i get "not responding" on a very regular basis, usually only for a couple of seconds but highly annoying none the less.

Chrome works fine for me.

Try the Firefox 64-bit beta

I am using FF 3.5.5 and Win 7 Pro with no problems. If I were you, I'd uninstall FF including your settings, download 3.5.5 and start over. FF is a great browser but develops glitches over time.

I do this atleast once a fortnight (Full FF uninstall not just from the progs list) and then reinstall from a fresh download, my issues remain the same.

Are you using any add-ons? The Skype add-on (installed by default with a Skype install) was causing my FF browser to crash constantly. Disabling the add-ons one at a time until the crashes stopped was how I troubleshot it.

Since Firefox 3.6 is now Beta 4, I have downloaded and installed it. So far I can see no problems but it is too early to tell. The installation went smoothly and everything from 3.5.5 is still there.

Start FF in safe mode and let it run for a while. Skye extension is a well known culprit.

Some plug-ins may cause trouble too. I had to disable the "Next generation Java plug-in"

Been ruinning W 7 evaluation copy for several months and have FF3.5, no problems at all.

yes there was a problem with the Skype add on but seems to be OK now.

Suggest you contact one of the W 7 help desks. I have found them very good and responsive, and I haven't even paid for mine yet.

Hmm.. maybe that's why they are so helpful

Skype Extension! I wasn't even aware that it was installed. Does skype this automatically?

Probably got installed with something else you need to read all the things next to the check boxes
