Why doesn't the rotate gesture on my trackpad behave as it used to for switching between tabs when it works the same with all other programs besides Firefox? I changed the about:config to make the rotate gesture move between tabs, and it worked great for well over a year. Now it behaves erratically as described here: https://bugzilla.mozilla.org/show_bug.cgi?id=877598 It used to be very controllable to move one tab over, now it is erratic and moves quickly and to unexpected tabs regardless of how slow I do the rotate gesture. This is the main reason I use Firefox over Chrome and I would like to continue to do so unless there is no fix to this.
