why does my desktop version of Firefox keeps asking to download an update. I have done it several times and keeps doing this..?

The same loop hit my laptop last year.

Close Firefox completely first. Restart your PC. Next, grab a fresh installer from their site and run it right over your current setup. Don't uninstall anything first. Your bookmarks and tabs will stay right where they are. That did the trick for me.

Once it opens, go to Help, then About Firefox. Check the version number listed there. What version does it show now?

Thank you Oliver! Now it shows version 159.0.1 seems to have stopped.. We will see if it works from now on.. Take care!
