Firefox has a huge problem with redirect pop-up to ad sties & I've tried many blockers but all are very complicated to use cuz user have to manually block each ad but with this blocker, user just block 1 whole page altogether. A very effective ad-block extension :-)

This extension is perfect. It's very easy to use in its basic form but offers loads of extra options for those who want to personalise it further. The inability to instantly go to a "procrastination"-website is an effective component is avoiding procrastinating behaviour.

Atende a necessidade. Achei fácil de usar e não falhou comigo.

Just plain doesn't work for me under Firefox 59.0.2. I tried using main domain name, specific subdomain, and wildcards - just can't get it to work at all. Deinstalling.

Very simple to use, sleek UI, do what is supposed to do without any unnecessary options/settings/configs,etc...

Thanks for solving my problem !!☺️

This didn't work at all for me. When I added a site to block, it didn't show up in the list of blocked sites. But when I tried to add it again, it said it was already blocked.

Useless. Cannot be used for most abusive sites, for example https://push-news.systems as BlockSite will not accept it as valid link. Do the designer really think the abusive sites follow rules. The previous version would accept a single word to trigger rejection, and use of ? and * logic symbols.

It does not work. Every time you go out of firefox and go back into this app the page is wiped clean. It is a useless piece of junk. Why is is still being promoted here?

can not block this site https://anime9.stream/

Cannot get it to block any URL that I have added to be blocked. Just doesn't seem to do anything at all.

Utterly useless piece o'c**p!

Will not block sites or stop them from opening another tab even with multiple variants of the URL in the 'database.' Can't even stop second order openings. Useless (Yes, it is toggled on)

I really hate to give a crippling review, however, I expect software to work, not take memory and CPU cycles in return for nothing.
