Rated 4 out of 5 stars

Definitely doing something - what, I'm not sure. FF drops to 14M now when idle, but then jumps up to 159M for little apparent reason. Also, some instructions would be helpful, like how to "view task manager in sidebar", how to configure for other apps, etc. Sorry if I'm dense, but these things are not clear to me.

This review is for a previous version of the add-on (1.4.5).
