Rated 4 out of 5 stars

I'm not exactly quite sure why, but it's caused many addons to stop functioning for whatever reason, leading me to about 2 hours of somewhat stupid troubleshooting, before I disabled and re-enabled it again which brought it back- Addons affected were Hola, DuckDuckGo Plus, Twitch Fox and Tab Memory Usage.

Otherwise, it has been really reliable to me, especially with Tab Groups' use of session recovery back up aiding its own broken system.

This review is for a previous version of the add-on (0.8.1.13).
