"Firefox has stopped working" occurs frequently


Recently FireFox has begun crashing repeatedly and at unexpected times. Simply presenting me with a dialogue box saying 'FireFox has stopped working'. Vista 'tries to find a solution' but to no end.

The crashes seem to occur exclusively when new websites are opened, or when I trigger some means of new data transfer. For example, I can load a website successfully and leave it up for hours without crashing, however if I were to click a link from that page it would most likely crash.

No particular websites appear to cause the problem. Even clicking simply links from Google can cause it. Yet the same link a few moments later on a second try can work fine.

Finally, it seems that FireFox is causing other applications - that use it - to crash also. For example if I click a link that opens Windows Media Player, some times WMP will 'stop working' in the same way. If I download files and then attempt to open file location via FF's download box, Windows Explorer will 'stop working'.

I do not have any crash reports available, but help would be greatly appreciated.

I got the same problem after I installed Thunderbird. So I uninstalled it again and FF is working again.
