This amazing!

I use this extension to make some bad/dangerous sites "not work" (analog hosts file), but unfortunately they continue to open.

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.

very convenient for people who really struggle to learn useful knowledge on internet

Complex but incredibly powerful. Has helped me stay more focused and scroll less.

You guys are the best! This is something I was forever looking for. Block the website, easy to use and custom messages. Just perfect!

I've used several tools for helping me focus while working. This one is by far the best I've found. It allows me to set up my limits while I'm feeling strong so that I don't cave in my moments of weakness.
