it's a great tool for helping concentration. I have one critique though. It first allows loading the blocked page, then a block screen covers the page. It would be less distracting if it doesn't load the page at all. I know it might require a completely different way of implementing the logic, but would be a nice addition.

I don`t know how but I lost my notification sounds. Tried re-instaling extension and it didnt help. On Edge its still working fine.
