Best find for Android. A blocker that works on mobile Firefox. It's super lightweight and, most importantly, completely non-intrusive – no annoying ads or popups.
The 5-rule limit on the free version is very fair because you can just swap rules whenever you need. I just treated myself to the pro version since there's a sale right now.
My wish for the future: a built-in Pomodorro timer and the ability to create separate lists for different tasks.
Thanks for a clean tool!

UIがきれいでわかりやすい！

This works so well and very easy to use. This was desperately needed for mozilla firefox browser. This works flawlessly unlike others. Thanks for Developer. People can now save time from addictive websites.

Thank you so much. I kept visiting the same websites compulsively all day every day and now I can't anymore. It's really helpful for my mental health. And it works very well, I'm not having any issue with it. Take care.

great

Very good extension, I like that nothing appears if you enter the site manually (out of habit) and that there is no reaction when I click a link in a google search.

Works well.

Perfect plugin! Been looking for something like this for months. Thanks Mark!

Absolutely excellent extension, thank you Mark.

Took me a sec to realize the websites are blocked but there's no notification for it. Works as intended.
However the UI could be done better. I want to add new rules from the top instead of scrolling to the bottom to add them

Edit: gave a star for prompt response and the new update

It works well and is easy to add rules. Took a bit of time to figure out the managing of extension.

An extension helps stay focused on work. It's easy to block the sites you want.

Практично и удобно. Пользуюсь сам, рекомендую.
