Simple good extenstion, does what it promises. Would be 5 star if there were an option to play a sound as it is indeed easy to ignore the popup after a while.

I like the idea of this add-on but it does not seem to work properly yet. After the first 60 minutes it keeps reminding me to take a break instead of reminding me to blink.

Would be nice if it would play a sound, as it it easy to miss the popup.
