After testing so many different distraction reducing apps, extensions, etc, this is the by far the best one i have found on any platform. It is incredibly detailed and customisable, with a focus mode (lockdown mode), different block sets, time based blocks, usage limit based blocking, customisable overrides (including limits on the duration and number of overrides), blocking pages, and so much more. My only wish is they turn it into an android app with similar functionality!

I find that this extension is very helpful for keeping myself from going to time-wasting websites while working on class assignments. The lockdown function is very useful.

Phenomenal. Helps prevent me from doomscrolling on Twitter and Reddit.

Simple and useful. Has improved my life significantly by blocking the websites that try to make it worse :)

works very well

Way better than Block Site, that addon is awful

I like this app. Helps me a lot :)

Thank you for helping me break the habits of constantly checking the cesspool that is Facebook & reddit. I am much happier when I let leechblock do its thing

amazing productivity extension that can block sites and also can let you set a specific timer before it lets you access a site

This extension is a lifesaver in the modern landscape of every single website ever trying their hardest to keep your attention for as long as possible

Awesome!
