Bagus

This extension really helps me control my social media addition. Thanks to the author!

Works like a charm, has all the features for free

Справді ефективний додаток, особливо під час екзаменів. В ньому неймовірна кількість різноманітних налаштувань, хоча з ними треба розібратися. Інтерфейс надто простий, але це не відміняє користь від додатку

Saved my finals

it's a vewy good boy. Is clean, does it's job well.

Very useful! Has many options to suit practically every desired blocking conditions. The only big flaw for me is that on Android, it keeps counting the time when the screen is locked or when I don't use Firefox. This is due to Firefox not allowing add-ons to detect that. My workaround is to close the browser when I don't use it. It also saves battery.
I donated to the add-on developer.

the best one for people who just want to get their work done

Great extension, really helps me!

Works really well, a bit unclear on how the time budget (time limit during time block sets...) function but you can figure it out with some searches and careful reading of the configuration.
