Pretty good, I find it useful to help keep me on task. Nice, simple to follow UI. My only issue so far is that I can't block GMail web addresses.

I tried lots of similar plugins. This is the best for procrastination because it prompts thinking about the decision. When I used LeechBlock, I could set it to make it *hard* to go to a site, but when I wanted to go, I just went through the hassle and it became part of the process and that's that.

My one complaint that is huge for me: there's no dark theme for PawBlock. The bright white background is just awful for my set up. Five stars if that could be fixed.

it works, although you could put a password or user to access your add-on and that this is not deactivated by others, or that for the add-on to be disabled ask for a confirmation password, or make block the page (about: addons) with password. thank you
