Tab Countdown Timer

Superbly simple. From installation to timer running in possibly, 15 seconds. Thanks for your work on this Jeff.

Used to work very well on my computer but no longer seems to function for some reason, Running windows 10. The timer simply doesnt activate when you plug in any numbers for me.

A perfect timer for those who want to remove their unproductive habits and start effectively using time.

An older now removed extension did this, I've missed it since. Its perfect for falling asleep to longer videos/streams. Thanks!

Working on a Chromebook.Thank you very much!
