After firefox automatically updated to version 11, I get an error when I shut down firefox:

firefox.exe - Aplication Error The instruction at :0x7c809af1" referenced memory at "0x00100000". the memory could not be "read". click OK to terminate the program

When I click OK the same message pops up. It will not allow the system to shut down I have to huld in the power button to force a shut down. I have tried a clean install including deleting the mozilla folder and it is still happening.

Hi,

Please check if this happens in Safe Mode. If the problem persists, please also try to Disable the Plugins in Tools (Alt + T) > Addons.

Problematic Extensions

Troubleshooting Extensions and Themes

Uninstalling Add-ons

Uninstalling Toolbars

Safe mode disables the installed Extensions, and themes (Appearance) in Tools (Alt + T) > Add-ons. Hardware acceleration is also temporarily disabled - the manual setting is Tools > Options > Advanced > General > Use hardware acceleration when available. Options > Advanced. All these settings/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme or hardware acceleration is causing issues.

It is possible that plugins aren't unloading properly, so also check for problems with plugins.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
