I have been using this for a long time, and it works very well.

This add-on is so user friendly that I set it up on computers when I help people do browser installs. For the people who cannot configure their own browser correctly, this is user friendly enough to not notice, so it is a giant win for privacy.

Great add-on! If it's created by the Electronic Frontier Foundation and recommended by PrivacyTools.io, it's good on my book. If you haven't checked them out, they have other solid privacy recommendations.
