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.

very nice add on works fine

It works exactly as described and it blocks what I need it to block.

Please fix Active Hours. I have to manually switch off the extension at the end of my working day!

good

Funny and great in use.
Checked if it works...one...two...three times^^

Active hours doesn't seem to work. Will amend review if it's fixed.

It blocks sites, right click and a hostile site is blocked there after. It works.

One improvement I would like is to be able to structure the sites that I block so that when the sites reappear with a slightly different name e.g the http://safety.microsoft.com..... etc sites I could add http://safety.microsoft.com.* and block them all

i love this its great a website called 403 forbidden or something always used to come up witch had pictures of disgusting things so my brothers/cousins and friends used to laugh at me and i got in big trouble, it used to automatically open and thanks to this it'll never come up again thanks allot its great that's why i rated it A BIG FIVE

very nice

Works very well.

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

It's really great! One thing: I have not been able to figure out the active time intervals. Maybe it's me or maybe it's not working. Other than that, this is great!

for simple on/off blocking this is fine, but the scheduling functionality does not work

good

Does everything it says it does perfectly.

It works.

It doesn't work. That's all.

I'm using this extension to prevent myself from wasting time in social media when I should be thinking about my work. Hopefully I resist the temptation to disable this addon :P
