Even in safe mode I just got the classic XP message "An error has occurred". I then had to uninstall Firefox and reinstall it. It works now and when I check for updates, it says there are any. It may have been a one. But the bug needs to be fixed. Reproducible: Couldn't Reproduce Steps to Reproduce: 1.I have no idea. Sorry 2. 3. I'm using the default theme.

sry 4 my spelling mistakes. E.g it says there aren't any updates. May have been a one off.

Thanks, I guess I'll have to do the same. Henry

Possibly the same root cause as Bug 443214.

Not blocking until we can confirm what's happened, or if it's a common occurrence.

This could happen because of bug 353804. Has this ever happened again for you?

Nope has never happened to me again, so it may be safe to close this bug. Sorry for not replying in ages.
