Great

Does what it says! When I encounter problems, it's easily deactivated on page-to-page basis. And it is easy to troubleshoot which "essential" tracker is being blocked.

Works hand in hand with ublock origin, can't complain

So easy to use, and it does a great job at keeping my browsing data private from third parties. +1

Makes the web seem much safer. Keeps spam from happening related to a visited page. For example when I checked a Bank's interest rate, the next day I would get emails offering differing interest offers from other banks. I had to make multiple rules every day, must have 50 or more such rules. Takes Thunderbird 5 minutes to delete those email during which the program is not responsive Yes, need a new address, but have many interests, takes forever to go to the sites, change that email address

It golden

This should just be a default extension when you install Firefox. Simple to use, and improves your privacy immensely.

Works well as intended.
