I recently updated Firefox from v29.0.1 to v30.0. Each time I exit the program, the following dialogue box is displayed after the Firefox window has closed:


Firefox has stopped working

A problem caused the program to stop working correctly. Please close the program.

[ Close the program ]


When I reinstalled v29.0.1 the problem stopped.

Until v30.0 all Firefox updates have worked with little or no problems.

Anyone else having this issue?

Thanks for your quick response.

However, I found the problem late yesterday evening. It is with my anti-virus/malware program, "Webroot SecureAnywhere."

In the "Identity Protection" section—under the "Application Protection" tab—the setting for firefox.exe (in c:\program files (x86)\mozilla firefox\updated) was PROTECT. Changing the setting to ALLOW solved the issue with exiting Firefox.

Apparently with Firefox v30.0, Webroot sees this as a totally new file and places the setting at PROTECT. This is the only explanation I can come up with since previous Firefox updates never exhibited this issue.

Other than the update to Firefox 30.0, no changes were made to my Firefox profile or PC's system.
