This could be 5 stars if after you put it on pause, the site you have blocked would shut down when the timer ran out. As it is, you can navigate anywhere you want on the site you're on when the time runs out, as long as you don't leave that site or refresh the page. Not good for stopping rabbit holes unfortunately.

Thanks

Does EXACTLY what it says it does. AMAZING add-on! Thank you!

very good

Very good for......blocking impulses!!! Nice and simple, no annoying messages as with other site blockers, just a clean simple set-up. I likey

При аварийном выключении Firefox высвечивается пустая страница дополнения, на которой ничего нет. У других дополнений такой проблемы нет.
С недавних пор вообще перестал работать - белая страница, переустановки не помогают.

Great and simple add-on , however If I allowed a blocked site for a certain time , it doesn't auto block it after the countdown is finished , the page has to be refreshed to allow the addin to block it , would be really appreciate to fix this minor bug and thanks for the addin :)

Simple, easy to use, easy to understand, very effective, customizable website blocker.

Simple add on; does what it says. I like to have it on my work computer.
