One of the best add ons to firefox ever created. Definitely recommended!

this has saved my brain and my productivity, thank you!

Improved my mental health, I have been using it for a while now and I appreciate it.

Helps me to fight my Youtube addiction on both Desktop and Mobile.

This extension is fantastic. Why I haven't found this earlier?

It became my habit to open Facebook. Most of the time I don't even now when I have opened the tab. Now with this extension, I open Facebook only when I actually need this.

Simple and very useful!! I recomend this add-on!

awesome, simple and complete feature

good

Free, open-source, with massive abilities to counter many different ways in which you can try to bypass it.
10/10, it only lacks some kind of automatic synchronization with a cloud service like google drive/nextcloud, but still an amazing first-install extension
