Description of problem:
I'm using a fully updated Fedora 18 with Firefox. Over the last week since I started using Fedora 18 (fresh install, no upgrade) I've seen it happen two or three times that Firefox and X after it completely freeze if I click a URL which is opened by Firefox.
The mouse cursor and keyboard become unresponsive. There is no realiable way to reproduce it, but it only happens if I click a link which is then opened in Firefox. The URL which is opened doesn't seem to have any effect, last time it happened when Firefox opened http://www.werkenvoornederland.nl/ which is a legit website. On that occassion I clicked the link in an e-mail I had open in Evolution.
All I can do is hit my PC's reset button. After a reboot I don't get any error messages, only the "Oops, this is embarissing" question from Firefox if I want to restore my tabs. I did have 15 tabs or so open at the time of the crash.
In this topic – http://forums.fedoraforum.org/showthread.php?t=282221 – on FedoraForum.org others seems to describe exactly the same issue I experience, but they don't mention existing bug reports.
Can you please attach Xorg.0.log (and Xorg.0.log.old) log files? There should be the info about X crash.

Here you are.
Ahh, sorry, I mean Xorg.0.log and Xorg.0.log.old files when the Firefox crashes. A crash log should be there.
Okay, I kind of expected that because I didn't read anything unusual when I uploaded the files :)
The problem is that I haven't seen a crash occur during the last one or two weeks. I guess I'll just close this bug for now and reopen it (and attach relevant X.org log files) if the crash hits me again.
