Rated 4 out of 5 stars

Nice simple restart Add-on, inserts a restart option in your menu and you can drag the button using customize on to your toolbar. I'm using FF4 with W7 (x64bit) and the Alt+F+R shortcut is not working for me?

Also, the developers should mention the fact that this Add-on WILL restore your tabs, some restart Add-ons don't. This is not mentioned in the description so I kept ignoring this Add-on until I read Ourben's review.
