hello, please install the search reset addon - it will revert the most common customziations those adware programs do in firefox back to the default: https://addons.mozilla.org/firefox/addon/searchreset/ if your settings don't stick after a restart of the browser also go to firefox > help > troubleshooting information > profile folder - "show folder", then a new window will open up. in this window look out for a file named '''user.js''' (it might be used to overwrite your custom settings). in case it is present , delete or rename this file and restart firefox afterwards.

Thank you very much
