Rated 5 out of 5 stars

Broken in 3.7a4 (despite overriding version limit). Was working fine in 3.7a3.
Love this extension though, just for the snappy. Nice little bonus is if you'd like to deactivate already open tabs you can slip into private mode and back out and all but the foremost tab go back to being inactive or "On tab". Great extension. Good work. Looking forward to seeing an update soon.

This review is for a previous version of the add-on (1.3.2). 

try the beta

Thanks for the feedback! I'm not committed to 3.7a* compatibility at the moment, but the latest 1.4b4 beta fixes at least the biggest problems with 3.7a4.
