1637115 - Mouse4 and Mouse5 translate to Mouse3 in Firefox on Mac OSX

Status: RESOLVED DUPLICATE of bug 1615213

(Core :: Widget: Cocoa, defect)

Description

[sahiltalwar88]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

I am using a mouse with 5 buttons, with button4 and button5 expected to correspond to backward and forward, as per the norm.

Full disclosure: I am using Barrier, a Synergy fork, and the mouse is plugged into the Windows machine and being sent over the network to the Mac. However, I don't believe that's relevant, because mouse4 and mouse5 translate just fine into other applications.

Actual results:

On Firefox 75 in OSX Mojave 10.14.6, they both translate to mouse3 and bring up the scroller thing (what happens when you click in the mouse wheel).

Expected results:

Mouse4 should have translated to "Back" and mouse5 should have translated to "Forward".
