Discovered this project froma post on the BunsenLabs forum -
LibreFox - firefox with privacy (https://github.com/intika/Librefox)
Interesting project for those concerned with privacy.
Of note, it appears you will want to start with a clean Firefox profile, so any existing firefox and user profile need to be deleted.
Used a bit yesterday, no performance hit as far as speed or watching videos is concerned. Didn't have time to really test it out though.
