Native mouse gestures on desktop

[wyvorn]

Please implement native mouse gestures in the desktop browser (I am personally on Windows) like in Opera. The current implementations from add-ons are very unreliable, finicky or don't work at all in some placed, e.g. in a New tab, Settings, while the mouse is over a video (in YT, for example) etc. Thank you for considering it.

We discussed this feature in our APZ (Panning and Zooming team) meeting and I wanted to share a couple of findings / updates from that discussion:

• There is a tracking bug on file for this at bug 1413874
• From an implementation point of view, while this feature has some similarity to the touchpad swipe-to-navigate feature, it's not linked to scrolling in the same way (the mouse gestures do not have the possibility of causing scrolling which needs to take priority over the gesture), so this feature does not need platform support. Rather, it would make more sense to add support for these gestures in the browser frontend.
