I have had AdBlocker as an add-on to my Firefox browser for the past couple of years and been very satisfied with it. When I need to reinstall my browser, I make sure that AdBlocker is the 1st add-on I enable before I do anything else. Strongly recommend it for reliability of performance and quiet diligent work it does in the background blocking annoying adds and popups. Congratulations to the team who created this add-on and made it available to the users free of charge.

Blocks add :-)

works well

Great!

Coming from Ublock Origin. I like this one better.
