Seems to show only 1 address though 2 are set. Also, doe not work.

Was a good add-on, now it's crap that doesn't work.

best block any site which we you choose...
also have a pop up menu from where you can block site after clicking right button on that site link or button

Doesn't block links as promised; at least in my experience!

Worked fine for me. I don't know what others are talking about, maybe the problem was during update, or they're stupid.
-2 star because it blocks the site in the URL, After you've clicked on it. The website is added to firefox's history, including the back button. Which causes the back button to loop. I assume(not tested) that it would fail to block the site if it were embedded in another.
I expected this blocker to remove and/or disable links in all active html/pages I was viewing. I need a PRE-blocker, not a POST-blocker.

Great extension, does what it says

it works . i was being tortured by constant redirects .most not connecting just flashing .no more

Не работает! Блокирую Youtube тут же обновляю страницу сайт ЗАГРУЖАЕТСЯ! Блокирую через ВАШУ кнопку Добавить в черный список

Does what the name says.

Excellent productivity tool, works exactly as intended.

On firefox I had access to password sites I want to access but block for kids that's a plus but on chrome there is not that option but is an option to block sites with a given word which firefox did not have. If I could get both features on both browsers 5 stars. Otherwise great for my needs,

Excellent add on and very useful.
