Truly brilliant addon with all the functionalities you would need. Would LOVE to also have this as an app on my phone, which you can sync with my desktop!

Works really great, helps me focus a lot! :)

Very good apps

Excellent propose toutes options nécessaires et imaginables ! Par exemple je peux bloquer facebook.com sauf facebook.com/events ce qui me permet d'avoir encore accès aux évènements (notamment les anniversaires) sans me faire prendre par le fils d'actualité

Straight-forward, clean, no fluff, works as intended. Makes you more productive. Hint: DO block that options page.

One of the best site blockers I've seem. I enjoy the amount of options, the way you can set up barriers for yourself (like password protecting), allowing timers for some website but not all, a time block that can be different for each website, etc.
Not only I'll continue using this extension to stop opening reddit and youtube when I should be working, but I will also set up timers so I don't waste more than 5 minutes of my free time scrolling endlessly on twitter and hackernews.
I can recommend this to almost anyone, since all features are free, easy to understand and can fit all type of user case.
Great job.

Does a good job at protecting me from some bad websites, that tend to open new pages through some evasive scripts.

I've been using Ublock to block myself from time-wasting website in the past

but it's just a deterrent, this add-on might still also be a deterrent (cause I think I can still manually bypass it?) but letting me put in the duration of the lockdown makes me not want to actually break it

Does what it should do. Blocking me from extraction or make it harder to visit Sites I shouldnt be visiting right now

It works! Perfect for me.

Very nice extension for focusing on the things you have to do, without outside distractions. Furthermore, it has multiple different options that can be used to personalize your needs beyond expectations!

Does exactly what you need it to do, helps keep those nagging social media sites one step away while you work.

LeechBlock is the best extension I've used for this purpose. I don't think I would have gotten my degree if it wasn't for LeechBlock preventing distractions :)
