hello mandy9291, you may have malicious software present on your system. please perform all these steps:

  1. reset firefox (this will keep your bookmarks and passwords)
  2. afterwards go to the firefox menu ≡ > 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.
