I have been using https://wiki.mozilla.org/Software_Update:Manually_Installing_a_MAR_file to update Firefox.

However, it has stopped working recently; although, there is nothing I've changed.

This is the error I get now:

PATCH DIRECTORY C:\TEMP\Firefox INSTALLATION DIRECTORY C:\Program Files (x86)\Mozilla Firefox WORKING DIRECTORY C:\Program Files (x86)\Mozilla Firefox failed: 23 calling QuitProgressUI

Any one else experiencing the same error? Anyone can confirm if it still works and Mozilla didn't deprecated it? Thank you!

Some protection programs don't like the update/install stubs. Download Firefox For All languages And Systems {web link}

Are you updating manually?

Can you describe all steps you use to update Firefox and the content of the update.status and update.version files?

Note that Firefox needs to be closed if you update Firefox manually and not from within Firefox.

Yes, Firefox is close when updating manually. Tried running as Admin and without Admin, but same result. Thanks!

I'm using PowerShell for scripting and these paths

$updaterFile = "C:\TEMP\FirefoxUpdate\updater.exe" $tempFolder = "C:\TEMP\FirefoxUpdate" $FFpath86 = "C:\Program Files (x86)\Mozilla Firefox" & $updaterFile $tempFolder $FFpath86 $FFpath86

You can try to remove the updater.ini file to prevent Firefox from showing the progress because the required stings are not available.
