When I click on Firefox the first time it says "Foxfire is installing your updates and will start in a few moments…. (with a green bar)" then it says "Software Update Failed (in blue) with an exclamation mark inside a yellow triangle) The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again." When I click the ok, Firefox opens up. If I open another Firefox window with the previous one still running, it doesn't give me any of these messages, it just opens normally.


This happened

Every time Firefox opened

Chosen solution

Becky, the following should fix this problem:

After closing Firefox, Remove the files in the updates and updates\0 folder: C:\Documents and Settings\<user>\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox\ C:\Program Files\Mozilla Firefox\updates\

(Replacing <user> with your Windows user name.)


If that doesn't work, try downloading the Firefox installer from http://www.firefox.com/all-older.html and running it, after exiting Firefox. Your settings won't be lost with this upgrade install.

I've tried all the recommended solutions for this problem apart from ending processes from fear of not being able to restart them. I also tried downloading another version on top of the existing one but I continue to be asked to close Firefox. I do not want to revert to IE but I'm stuck with it at the moment. Help please.

If you can't install on top of the current installation then you need to delete or rename the current Firefox program folder to do a clean install.

It is possible that your security software is using or locking files, so you can try to temporarily disable that software during the installation.
