Rated 5 out of 5 stars

YESS. It works perfectly. Great for sites such as facebook which often have problems when they're overloaded. I knew somebody out there had to have made this extension already! I think you need to add some more tags for searching for it though - I tried searching 'auto refresh" "Auto reload" and a dozen other word combinations before finally finding this. Also, like Derom mentioned , an option for 500ms or 250ms would be nice.

This review is for a previous version of the add-on (3.1.0).
