No but it's similar I have Sandboxie ( www.sandboxie.com ) it I have it configured to disable history wile using it but my Firefox's history is enabled so do you think this causing some sort of conflict? Note: I also save settings,themes,personasand the sd thumbnails folder outside the sandbox oh and I have cookie disabled in the sandbox as well. Thanks for the quick reply.

Is Firefox still Crashing when you use Firefox 11 ??

Yes it is.

Start Firefox in -> Diagnose Firefox issues using Troubleshoot Mode to check if your add-ons/extension are causing the problem.

• Also see this article -> Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Check and tell if its working.

Well I could re enable my plugins there not going to effect it much right? One other note I modified my FF to store 60 persona's and currently I have 55 I made this mod around November/December 2011.

Does your Firefox Crashes when using Firefox in -> Diagnose Firefox issues using Troubleshoot Mode ???

I'll disable the extensions and come back in to this post in a few days because the thing is that it doesn't crash every time I close it although there does seem to be a pattern to it about every 5-7 days it crashes when I close out of FF.

The crash report seems to be related to shutting down NSS (security device) that handles secure connections and other cryptographic services.

You can try to create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Could a DNS redirect cause this to happen?

New crash ID bp-1a272e53-ce3d-4b94-8ac7-776172120515 so whats going on now I disabled all my extensions and I don't exactly understand how to create a new profile couldn't I just do a complete reinstall AKA remove all settings and personal data? And then using Mozbackup restore my passwords and bookmarks?

You can also check for problems with plugins.

See:

I just updated my Adobe Reader hopefully that fixes it I let you know with in the next 7 days.

Well its been over 7 days and no crashes so I'll wait another week (the 29th) and post an update but I think this problem is solved either way I let you know soon.

Awesome its been over two weeks and it hasn't crashed so it's definitely fixed so all I had to do was update one of my plugins (Adobe Reader) and make some configuration changes to my Sandboxie (allowing it to save history and cookies outside the sandbox) then disabling them from within Firefox so if anyone else is having this issue try updating your plugins and if you have Sandboxie try enabling the history&cookies as well.
