hello, you have a user.js file present which will overwrite your manual changes after a restart of the browser, please try this: go to the
- firefox menu
> help 
> troubleshooting information,
click on profile folder - "show folder", then a new window will open up.
in this window look out for a file named user.js, delete or rename this file in case you haven't intentionally created it in the first place and restart firefox afterwards.
in addition you might want to 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.
