Rated 3 out of 5 stars

This hasn't been updated since 2011. We're in 2013. I am guessing this doesn't work anymore with the latest Firefox versions, 20 and 21 Beta 3? I would like to have this feature. I heard it's in some mouse gesture addons. I use Fire Gestures, but I don't know if it has that feature. I will have to check it out.
