Learn basic regular expressions and this becomes an amazing anti-distraction tool. You can specify block times separately per day & even use custom redirects.

The best app ever to protect yourself from your porn addiction. You have to add the sites manually. Remember to activate it in private windows.

Amazing just what i was looking for.(been looking for something like this for months) thanks

Best extension to avoid distractions by blocking the websites.. I am detoxing myself from social networking platforms..

Best blocker extension for me. A big improvememt would be to sync the settings across different browsers.

I went out to do errands, came back to it, now it works

Thank you for your extension!!! I hope Mozilla not remove it. They don't have any password to firefox for our protection. I think there is a problem here. If I close the extension and open it again, the addon closes all block sites. Can you fix this?

I wrote a css override to make it more encouraging.
The code below makes the custom message you write look fancier, and removes the discouraging ! sign. I'd much rather block sites gently.
Thank you for such an awesome plugin though.

This is the best site blocking add-on.

The new(er) version does not work well, after I load all my blocking page via a textfile, everything is working. But after a restart, I can see the blocked site, but when I click on a link from a blocked site (going to a sub link) it start blocking. When I save for example a new website to block, everything is working good again. But after a restart same problems. In the past I used it with succes, but now there is something not quite right.

So far so good in the first 5 or so minutes. I needed it to stop me from accidentally watching any video sites while having a VPN with limited gb per month available.

Fantastic! Does exactly what it says and there's lots more under the hood. A pity it's not compatible with Firefox Mobile.
