Whenever I accidentally scroll too far left or right in Firefox, it goes back or forth in my history, which is very annoying. How could I disable this?
I have this behavior on desktop specifically on the laptop trackpad's 2finger swipe gesture, which seems to be used for both scrolling as well as back/forward. I do not have this behavior on other input devices' methods for scrolling (e.g. mouse wheel horizontal scroll).
In the about:config page there's an option named middlemouse.contentLoadURL. If you set that to false, it seems to stop the middle mouse click from going back to the previous visited website.
I honestly have no idea what they're talking about. Neither desktop nor mobile have this behavior. Maybe he's talking about the Android gesture that replaced the back button when they removed the bottom buttons?
