Rated 5 out of 5 stars

I thought I would look for an extension like this, so whenever I accidentally close and remember having to do something else, I don't have to wait for Firefox to load again :) I have to open if from the tray though, but that is to be expected with desktop launchers etc

Firefox 35, Fedora 21 Linux

This review is for a previous version of the add-on (1.1.2.1-signed.1-signed).
