So the new privacy policy says that they collect your browser history including sites visited.

So fuck that, not gonna touch this shit.

Also it lost my list of sites during the update.

The time of day settings do not work.
Stops working at all after a couple of days/weeks.

I really liked this add-on for a day. Then I opened two windows on firefox and add-on was completly useles on the other window. I was able to reach blocked web sites. While this bug remains one star out of five will remain too.

Rubbish extension! My kids can still access blocked sites! I set a parental control with a password I am CERTAIN of yet it says again and again that it's the wrong password. So now my kids can still use the 'blocked' pages and I can't get into the controls. Bye bye silly app.

Doesnt save the blocked sites.If I close Firefox then re-open it I have to import the block sites again

It doesn't work. That's all.

It is rather a very poor user experience to ask him/her to type the url. Why not design this add-on to allow to add it by click on the tab and extract the site info directly?
Also, I noticed that typing the domain like domain.com won't block landing.domain.com. What is the point then? The malicious web site admin can create a second site like landing2.domain.com and go on business as usual.
I really liked to try this add-on at first because I wanted to avoid editing the hosts file directly.
I would appreciate if the developers listed to this feedback.

Will not keep blocksites in browser so have re-add it each time, whats the point? Each time browser starts have to add blocked sites in again. Totally pointless and shit add-on

blocked my homepage , can't unblock it ....thanks for the pain

doesn't work at all

Don't download it. It doesn't work at all.

doesn't work at all. still full access to sites.
(using FF Developer Edition)

Does not work on Firefox on Windows 10. Please fix.

Using firefox 59.0.2.
The add-on doesn't seem functional. I'm able to set all of the settings and the interface seems to work, but I'm still able to access blocked sites. I've tried restarting to double check.
I'll change the rating should anything change.

It doesn't work on Firefox Quantum (59.0.2)

Does not work with Firefox.

Not working

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.

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?
