Effective and easy to use. I cannot recommend this highly enough.

Good stuff, mes amis

It was working amazing till today, when it gave me access to a blocked site again(I generally tried to open the site when I got distracted, saw that leechblock blocked it, and went back to working.). I went into lockdown and manually locked down for 100 hours and it locked the site down again. I don't know how it gave me access to that site though.

Firefox 68 user here. Leechblock rating reduced to 3 stars; stops working, does not block URLs reliably. This used to be a stable and VERY useful extension, but now (Sep 2019) it stops working altogethter every few weeks (fails to block any of my specified URLs). Removing the extension and re-installing sometimes fixes the issue, but only temporarily. Hopefully a future extension or Firefox update will fix the bug causing LeechBlock to suddenly stop working entirely.

Great Addon that helps me stay productive. Tons of features so you can finetune your own internet usage.

A free essential to help focus on studies, LeechBlock is just great!

veramente potente. forse fin troppo

Un bloqueur de sites complet avec option de verrouillage pour nous empêcher : de désactiver le blocage de sites, nous dissuader en nous obligeant à recopier un long mot de passe complexe. Si vous êtes étudiant et que vous cherchez un outil pour discipliner votre temps passé en ligne : c'est du tout bon.

It is wonderful

Excellent addon to block websites.
