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

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!

Does what I need it to, nothing more to say.

Absolutely wonderful Firefox extension. Many settings to tailor to your needs. Works as intended!

Very very good, helped with my procrastination
