I have no complaints, but one... Rated 5 out of 5 stars

Sometimes I restart Firefox when I have a few hundred tabs open with a lot of weather animations and YouTube videos. Then this restart causes an interruption of my Firefox uptime record, which is very unreasonable of course.
Otherwise no complaints, so this add-on is certainly worth 5 stars. Highly recommended!

This review is for a previous version of the add-on (0.1.1-signed.1-signed).
