I endorse anything that blocks my mind from floating off into... ehhmm.. zummmmm......

i like the addon, but I'm concerned about why does it need to "Access your data for all websites"?

The addon is really nice in the concept, but it has some problems.
1- Productive session are often terminated when they didn't reach the end and it is really annoying having to reactivate it each time.
2- Writing text has conflicts with other addons, often some keys don't work I believe it's caused by an extension using that key as shortcut

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.
