An amazing tool to boost your productivity. Also simple to use =)

The user experience is technical and can be confusing at first, but it has all the features you could need.

My God, I hate the access codes so much. It's perfect, thank you so much!!

Has every feature you can think off. Super glad I've got it. Not sure if I'm doing it wrong but it would be great to be able to set a block past midnight (2000-0200) for example. cheers for making this free.

Doubled my productivity

I like the feature: " Enter a time limit after which to block these sites (optional): "

This single extension helped me go from a 2.4 GPA student to a 4.0 and top of my college class in Statistics, Computer Science, and Math!

Es una aplicación sencilla pero muy eficiente, hace lo que se supone que debe hacer de una forma fácil y sencilla. Si me ha ayudado a concentrarme, creía que iba a ser inutil pero si me ayudó.

Quite Useful

Works perfectly after some tinkering

Great extension! I would recommend adding the ability to block/allow based off website tab titles, as there are some use cases involving Youtube that I could make use of :)

This is a powerful extension. I love that it gives me so many options to really customize what I need. Other productivity extensions give too much leeway, and while for some sites that's fine, LeechBlock helps me be more disciplined. For anyone who wants to be more productive without uninstalling FireFox all together, this is a great extension. Thank you guys!

Merci

A great little tool to curb your social media addiction

Honestly quite incredible

My cave brain typed YouTube.com while I was studying, this blocked it. Great work.

Easy to use

This is fantastic. It has helped me limit time on websites that were really leeching my time away. Exactly what I was looking for.
