I click to exit Firefox and the above error message & below this error message it says the following: The instruction at 0x776fe144 referenced memory at 0xfffffffff. The memory could not be read. Click on OK to terminate the program.

The only change I have made recently was to upgrade to the current Firefox version 30.0, the above message showed up after the upgrade.
