I use Firefox as a camera log in for recording sessions. Unfortunately, Firefox (on the Mac) has a "helpful" feature that navigates you back and forth through your history with Option-Scroll. Unfortunately, this is also the key combination to zoom in and out of Roll20. I am forever trying to set a good level of zoom and navigating out of the game. I have looked through all the base settings for how to turn this behavior off, with no luck. Likewise extensions all seem to want to give me MORE mouse gestures instead of just turning it off. Does anybody know how to disable this annoyance?
