Windows 7 SP1 Firefox 13.0.1

Upgraded to FF 13.0.1 with no problems encountered. The next day I restarted the system and installed the Windows Defender definition update released on 6/15 (11.27.2061.0 - KB915597) via Windows Update. After applying the update FF crashed immediately upon starting several times. I rebooted the system - no change. I then applied the restore point created just before the Defender update was applied, rebooted, and was able to start FF normally.

Here's the crash info from one of the crashes:

Does it help if you create a new profile or uninstall and reinstall Firefox?

If you reinstall Firefox then be sure to remove the Firefox program folder to remove possibly left over files in it.

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":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

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.

If files in the profile were corrupted, how would FF work fine after reversing the Windows Defender update (the only change that was installed)?

Surely a developer with access to a link map and compiler listings can see what the code at address 62245 is doing and narrow this search down a bit...
