L.O.L. This gets an instant 5-star from me!!

Quite ironically, I accidentally closed this tab immediately after installing this extension and was SO HAPPY to have this super-convenient little button right there in my toolbar!!!
(...rather than spending 5x longer trying to find FF's built-in version in my context menu, and I never remember my mouse gesture the first few tries...)

Also the mini recent history drop-down is an excellent bonus!
Kudos, and THANK YOU!!!
