This add-on is amazing! I use a lot of older computers, and run FireFox, as it is the fastest in my experience. The problem with it, is FireFox has no built in ad blocker, and ads can bring a computer to a crawl, especially an old one. This add-on does an amazing job at blocking resource hogging ads ad and pop-ups. I wrote this review on a 14 year old Dell laptop that can still surf the web thanks to this add-on!

Genius solution for avoiding ads. The only complaint I have is that after it mutes Spotify ads I need to refresh the page to keep listening to music.

Here's the thing: It does block ads, however, if my understanding is correct, if you let the site through, the site auto references to an "OK" list that does not revert back to the block setting next time you access the site. OK some might say I want that, others who may be searching or an occasional visitor, will NOT want that. The list is hard to access and difficult to process.

Bottom line for me this is this blocks all ads ONCE, after that you have to take the time to work it.

I am not a firefox or AdBlocker anything. Cheers!
