hello, you may have malware present on your computer. please try these steps:

  1. reset firefox (this will keep your bookmarks and passwords)
  2. afterwards go to firefox > addons > extensions and in case there are still extensions listed there, disable them.
  3. finally run a full scan of your system with different security tools like the free version of malwarebytes and adwcleaner to make sure that adware isn't present in other places of your system as well.

Those are probably scam messages that you should ignore.

You should only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page as that will likely infect you with malware.
