best block any site which we you choose...
also have a pop up menu from where you can block site after clicking right button on that site link or button

Great extension, does what it says

Does what the name says.

Excellent productivity tool, works exactly as intended.

Excellent add on and very useful.

I needed to block Roblox because it got very slow and in case I got frustrated with it. I will be uninstalling it and if I try and access it BlockSite will stop me which is awesome.

Excellent add-on !!

Love it. Would be nice if you could sync the blocked pages between different devices.
