Time Out : Page Blocker

I've been looking for an extension like this, the previous ones I tried didn't really work very effectively and even had paywalls after X number of sites blocked. As far as I'm aware, this extension has worked flawlessly and it's free! I'd be fine giving the app maker a tip given how simple and easy this has been to use.

Best extension for exams !!!!

Simple and free

work flawlessly ,btw good rick roll you got me!!! but can you add the functionality that allows me set different timer for different sites . It would really help.
