My favorite Firefox extension, ever! I discovered mouse gestures in Opera a dozen years ago and wanted this feature in Firefox. I found an extension simply called MouseGestures that was quite nice. And about a year later, i eventually found FireGestures by Gomita that made my web life so much easier, so much ergonomical, so great!!!... Then November 14th, 2017 came and the Quantum plague killed everything on its way... I'm so sad... I miss you so much FireGestures, thank you so much Gomita for all those years of web happiness and comfort!
