Great add on! Very useful to stay focussed on your work.

Happy it is back in the lasest Firefox version. I was wondering if it is suppossed to work in Firefox for Android as well? I tried to install the add on, and although the add on is running, the indicated websites are not blocked. Would be great to have it on Android as well :)!

Thanks!

UPDATE: Amazing, indeed it works in Android too. Love it!
