Why does my Firefox always display "Restart to Update" even though it's the latest version?

enter image description here

When I clicked on that, it just restarted and nothing happened, and the button's still there.

This problem first appeared in Firefox 16. Back then the same thing happened and when I clicked on the button, it just restarted and didn't update, so I had to manually download the setup file for Firefox 17 and install it manually

Use this method as per Mozilla Support

Please try this, ideally from an Administrator account: Search for all instances of updates.xml, right-click each instance > Open file location, check if it's related to Firefox and delete it along with the whole updates folder which would be usually present in the same location.
