Experimental Features

thanks for following up.

1. please go to the firefox menu ≡ > addons > extensions & remove those two "deals" addons, since they are likely adware.
2. also go to the windows control panel / programs and remove suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc) from there.
3. finally, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner, which are specialised in adware and browser hijackers.
