    Firefox update problem


    When opening firefox it prompts:

    'Firefox is installing your updates and will start in a few moments.'

    but after the bar runs through it gives an error:

    'The update could not be completed. Please make sure there are no other copies of firefox running on your computer, and then restart Firefox to try again.'

    I click ok and every time I open firefox it does the same thing.

    Firefox is not running I've rebooted, checked task manager, closed firewall, not really sure what is going on.

    If this is a firefox update, I run version 11,.. Updated windows recently

    Any ideas...?

    Just remove the old version (11) and make a clean install of the latest version (12) of firefox.

    Let me know if it helps.
