I am trying to update Firefox and I get a message that the update failed. There were problems checking for, downloading, or installing this update. Firefox could not be updated because FAILED (Unknown reason).

I restarted my computer and tried again and still got the same message.

What do I do to get the latest update?

Thank you.

Hi lansimivalley.

The update might be blocked e.g. by your antivirus software. From my experience, the fastest way is to download latest Firefox from http://getfirefox.com/ and install over your current Firefox (when completely closed, of course).
