Been looking to do something similar to this using dns etc. and I could never figure it out, this has been a life saver for me.

Best Extension!

very good

Works flawlessly so far for its function and it is completely free! Recommend a lot for everyone to help focus on more important tasks and limit addictive websites of all genres!

Very good on PC, but i wish there was a FAQs on how to make this extension more tight on the firefox browser for android.

really easy to use, helps a lot with my productivity

Excellent addon. Here's what would be really great if it was added. An option to use a override on the blocked page, so don't have to go through the addon menu. Pretty simple QoL improvement which should also discourage the user from changing other addon settings once out of set overrides.

It has helped me to overcome youtube addiction and save time in general

perfect extension for blocking distractions.

JoeBigThoughts over here, and I think its pretty good
