Excellent extension, but... Rated 5 out of 5 stars

This is without a doubt one of the best extensions I have. The only problem is that there is a fast and easy way to circumvent it, if you don't want to know it don't read: Leechblock works very well, except that you can easily just change the clock on your computer. I think an easy fix for this would be for you to select a time zone in Leechblock's options, then when you open your browser, it gets the time from the internet instead of your computer.

This review is for a previous version of the add-on (0.4.1).
