I do wish I could have it disabled by default when I open my browser. It would be 5 stars for that, but it does what it says and is good at doing it so 4 is good

If time usage blocking is added, would be perfect :)

Love the concept. Very simple and just what I was looking for. Only 4* as it doesn't seem to work with "https://web.whatsapp.com/". It's in the list of blocked domains but it still opens normally.

It does it's job well but the fact that it's enabled every time I open my browser gets a bit annoying when I'm just trying to relax. There should be a default option for when you open Firefox
