Rated 5 out of 5 stars

The addon is awesome. Although there are some things that is missing. For example, if you click a link on a website that is blocked, the time you spend on the linked website doesn't count! And also, if you are on a blocked website and the time is up, it won't block it until you reload the page.

Leaving aside those few missing features, the addon is excellent.

Active blocking

Thanks for the review! You're right about the first point (it might be implemented in a future version) but the second feature is already implemented. Look for the setting "Actively block pages on these sites..." under "How to Block" in LB Options.
