Firefox crashes/closes on websites with flash

Posted

This started yesterday when I was prompted to download and install the 3.6.7 update for Firefox. After restarting the browser, I get a message that it was not installed correctly, and then it closes without warning. It does not give the usual message that there is a problem and Firefox needs to close.

After experimenting, I've noticed that this only seems to happen when trying to load websites that include Flash content. Gmail and Youtube cause it to crash immediately. Other websites, like Facebook and certain forums will load initially, but will crash on certain pages, where there is probably a flash video or other application.

I tried starting Firefox in Safe Mode, but I still get these crashes. When I go to about:crashes, I get no reports of the recent crashes.

I still can't update Firefox to latest version, so I still have 3.6.6. Every time I try, the installation fails. I do have the latest version of Flash.

I believe I've tried everything suggested in the Knowledgebase, so if anyone has any suggestions I would really appreciate it.

i also had this problem.

i reeinstalled firefox (the newest version) and later shutdown the browser defender toolbar in de add-on section.

this did take care of most of the problems. (as in slow computer, problems with flash video's, very slow typing etc.)

computer 1 year old, very good threat, virus scanning system that says my computer is not infected. Everytime I get to a site, I get kicked off. FIrefox comes on with a page stating it's embarrased, and that I need to reload, etc. which I have done 20 times. Anyway, I'm still getting kicked off. I have even tried to download the lates firefox, today, but it states that I first need to shut off an open firefox tab. Please help, I'm going nuts trying to straighten this out.

Open up computer case, unplug and take out the processor fan cooler and wipe out all the dust, speccially in the heatsink, with a soft little brush and compressed air spray (also check power supply fan). I discovered this solution after weeks of trying all software related recommended steps and nothing worked, adobe flash player was still crashing in firefox, chrome and opera even after completely uninstalling flash and installing latest version 10.2.152.26 of the plugin. I realized this was the problem when pc started to crash unexepectedly when not playing flash videos. So, EUREKA, that did the trick for me. Hope it does for you.
