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?

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.

Nach einen Neustart ist die immer wieder leer, daher kaum zu gebrauchen.

works well enough - in one internet window. All i have to do to access the blocked site is open a new window, go to the site, and it allows access everytime

Does not work at all. I've tried a page refresh, new tab, new window and reboot. The site is still there.

Block Site doesn't block ads, it re-re-directs the opening pop-up pages to adverts for Block Site instead, which defeats the purpose.

Just doesn't work.

Just straight up doesn't work

Does not block groups of websites, so the browser slows down to some halt. Darn.

Doesn't block anything at all. Not on adding element and not after page reload. For those who want add-on that actually blocking elements on page use ABP, it doesn't have block dialogue on 100% of whole internet, but for those elements that have dialogue it works and blocking em instantly.

does not work

Doesn't work...

Worked fine day 1. Completely stops blocking on day 2. I don't even use any settings beyond the blacklist itself.

only saiful islam

Put in a website to be blocked because I got the message from Avast Antivirus "Threat has been detected." Refresh the page I was on, I still get the same message!

I really can't get this to work, and I'm quite computer-literate... I've blacklisted *.youtube.co.uk and *.youtube.com, with appropraite time-settings, but youtube just continues to open. I now can't add any more sites..! If I type something into the Add Page box, what's to do next? It just sits there. Very frustrating.

Schelchte Funktion. Sperrt nur direkt die Seite die man eingibt mehr nicht. Restliche Seiten können weiterhin geöffnet werden. Keine Dömainsperre möglich und keine Anpassungsmöglichkeiten vorhanden

worst not working

Pretty basic addon, it kinda works but the scheduler doesn't do anything, if you add more than a few sites you can't scroll through them. Low effort really

Occasionally fails and doesn't block sites. With an option to access it on the overflow menu, it's too easily disabled. There's a password you can set up to prevent easy access to that, but that fails 80% of the time. I wish this add-on works, but it doesn't.

extension dont work... when I click on a link, the program allows me to load blocked content, and then throws out its page with information that the content is blocked ... example ... (You have already tried 3 times.
Come on! Stop doing this. ) I clicked on three different links (different sites in the links) but got redirection to same page (http://eulp.m-engine.net/?lpid=LTE1NTY5NDA=&spro_id=80551636689661&meaff_id=2796#9)

its not blocking like it should
