This is always the first extension I install whenever I launch a fresh Firefox profile (or whenever I notice my friends don’t have it installed). It just works and makes the internet a much better and safer place.

I changed my primary browser to Firefox because chrome blocked this extension.

Never failed me. Consistent and effective. Just a great extension.
