This add-on helps, it has politely reminded me that I should spend only a limited amount of time on some web pages.

I am subtracting 2 stars because the add-on screenshot is different from real behavior, it has a large window with content:
"Add a 5 star rating...;
🙌🏽 Tell your friends and colleagues: ".
That window has pushed the main window to right side and is up to my face, for the past maybe a month. Finally that request managed to push me making a firefox add-on account and publishing this review because I have read that 5* review request for the past month every day, literally every minute (on some web pages).

Overall I appreciate this add-on, thank you.

Cool extension but needs an option to disable "cooldowns".

Finally, a "blocker" that encourages mindfulness instead of brute restraint and inflexible rules.

Really happy with the app and how its helping me focus and dont get distracted.

Thank you for saving countless hours of my life

Discovered this extension on Hacker News. I'm enjoying it! Works pretty well

This might be the one extension/app tht really works for me to keep focussed on doing my job. It's in your face and just customizable enough to make the right intentions.

Simple, but effective. Easy to use and stylish UI. Thanks for improving my life! :)
