Since perfection doesn't exist, I'm giving you 4 stars, but it's really good work, thank you. So according to Firefox you are not secure and efficient, that's why it doesn't recommend you! I admit that I'm worried.

I do like this ad blocker, but the reason that I gave it only 4 stars are for two reasons. The first reason is there are a couple of websites that I've put on the whitelist but I still have keep turning off the blocker in order to enable the page. If I don't it won't allow me to see everything or sign in to that site. The other thing is more of an annoyance than anything. And that is the pop up every time 1000 things have been blocked. I wish that would stop and if I wanted to see how many pages have been blocked, then let there be something when clicking on the extension if we choose to see how many things have been blocked since using. Other than that, I am happy with this site.

its work on Microsoft edge too slow. specially in "block elements" and manually added objects

Not bad

sometimes doesnt work on youtube

Some adds on YouTube get through. This is not very common, however, and otherwise it works quite well.
