As a student, I am very thankful for this free add-on and I use it everyday. It is extremely customizable to your own preferences.

Amazing productivity tool. Work as promised. Easy to configure.

Really helpful

Its not blocking anything no matter my settings. I went to the forums like the dev said but absolutely nothing came out of it. Its been months and this add-on still does nothing at all.

This add on is light and very feature rich. I love having multiple types of block categories, which I use to either block permanently, whitelist only on certain days, or to allow overrides which are very helpful. Overrides are awesome, for example, if the answer you're looking for happens to be on reddit or youtube, which happen to be two of the biggest timesink websites out there. I think there could be finer grained control over the blocking of date and time, but its more than sufficient for how I'm using it. I would highly recommend this addon to anyone who wants take back control of their attention from tech giants and their algorithms.

Extremly useful

Annoying when I want to access sites I want to use, which is perfect from accessing sites I don't want to use. I still don't know how to use the override feature.

This extension is absolutely the best tool for blocking sites that I might select because of an interesting ad, interesting article, or something similar that might lead me to subscribe to, waste my time on, or spend money on. We need to rate this with 6 out of 5 starts!

Only one I've come accross that can block all Google domains with *.google.com, including drive.google.com, accounts.google.com, etc.

Does what it says. Very effective

simple, unintrusive, fast cant recommend more exactly what I was looking for
