The script seems to work very well.
It's worth mentioning that you may need to restart your browser to get the "Shift+T" to work.

it helps alot if u worry about some scripts or something not responding while u sleep, thx. good work!

Works as expected. Very easy to use and exactly want I needed.

awesome. took me a few minutes to figure out what was going on, but perfect for automatic refresh, because of the modifiable preferences

Thanks for get it update.
