LOVE IT!!! PERFECT FOR STUDYING
NEEDS MORE DOWNLOADS, MORE REVIEWS, MORE LOVE, MOOOORE!!

I had no problems using it on chrome. Worked perfectly and helped me with keeping track of the time better. However after switching to Firefox, it rarely ever worked. Sometimes only the rain effects would turn on. Sometimes nothing at all ever happened. Read another review that said to download the desktop app and so far so good there.

The author of this extension has migrated to making a desktop app at nook.camp, use that instead!

a perfect app. the mozilla version will play the song sometimes when I start the browser on grandfather mode, though. it's not an issue just slightly less responsive than the chrome version. either way it's the perfect add on and helps me manage my time and attention, love you Nook add-on.
