Since upgrading to Firefox 6.0.2 it crashes a lot more often. Usually when I try to open certain pages, but I don't know what on those pages might be causing the crash because I can't read them.
I came to this site and clicked on the link to "Fix slowness, crashes, error messages and other problems" at http://support.mozilla.org/kb/fix-slowness-crashing-error-messages-or-other-prob - and Firefox crashed again!
I always tick the box to tell it to send the information to Mozilla, but I've never been sent a crash ID (AFAIK)
You can try to update Firefox to check if old crash problems have been fixed. If the problem persists after updating, you can also try to Reset Firefox via Help (Alt + H) > Troubleshooting Information.
Thanks, well I can now read https://support.mozilla.org/en-US/kb/fix-slowness-crashing-error-messages-or-other-prob so that's a good step forward
When did you upgrade to the old Firefox 6.0.2 as this was released back on September 6th, 2011 http://www.mozilla.org/en-US/firefox/6.0.2/releasenotes/ and the Firefox 13.0.1 is the current release.
Mozilla is not paying attention to crashes from such old versions like Fx 6.0.2 anymore anyways as the oldest listed is 10.0.3esr and 11.0 at https://crash-stats.mozilla.com/products/Firefox
