Perhaps you should manually update in a couple of steps, since your version (reported by your browser as 32-bit Firefox 72) is pretty far behind now.
For example, grab 32-bit Firefox 78.0.2 from here (this is U.S. English, for other languages, click the .. link and then click into the relevant locale folder):
http://archive.mozilla.org/pub/firefox/releases/78.0.2/win32/en-US/
Will that install? Then try the update again.
Note that in current release you can try to clear the startup cache via the "Help -> Troubleshooting Information" (about:support) page.
