I have been looking for this for so long, Thank you for making this add-on.

does what it says on the tin

The extension doesn't work properly unless you allow it to access your data for all websites. Ridiculous.

This amazing!

the add-on has saved me from being homeless

Best add-on!

The best productive addon i had ever seen in my life!!

Love the flexibility of this extension. Allows you to set up multiple block sets with their own rules, time limits, and schedules. Has settings to block or discourage you from accessing it's own settings, which has been great for stopping myself from just switching the blocks off like with other extensions. Requires some initial setup, but has changed my browsing habits for the better. Thank you!

Muy buena para bloquear mi adiccion a twitter.

Excellent for weaning myself off instant gratification sites like social media - I set myself 3 minutes per hour (enough to find out anything I need) and then get a 1 minute wait if I want to read more (enough to discourage me)

This was everything I was looking for in a blocking extension. Tons of options, different block sets, allowing for limited use times, days of the week, everything, and it's free.

Not so many years ago, it was unthinkable that some day we would need an extension like this! LOL. I didn't tested out fully but just for the thought of it deserved 5 stars. Thanks James!

Slowly but surely, my social media addiction goes away, all thanks to this extension!
(Tip: Use a delay page plus restricting time spent on social media sites)

The configuration is a bit too "techy" and clunky, but doable. Plus, once you're done with the setup, you rarely interact with the configuration anymore.
