Three finger swipe with firefox

[samcarter]

First of all: Thanks a lot for your bug fixes. I couldn't get the upstream version of jitouch to work on my M1 mac, but with your modifications it finally worked!

I'm using jitouch to remap the left/right three finger swipe to a specific keyboard shortcut. This works great in all apps with the one exception of firefox. If I change the gesture to something else, e.g. a three finger tap, the remapping will also work in firefox.

Do you happen to know why the three finger swipe does not work in firefox? I thought that maybe firefox monopolises the gesture, so I tried to disable everything in firefox about:config which looked related to gestures, but the there finger swipe still does not work.

Hello,

Do you have "Swipe between pages" enabled in System Preferences > Trackpad > More Gestures? It looks like Firefox picks up on that even if you have the three-finger swipe disabled.

Specifically, enabling the swipe between pages gesture sets this variable:

defaults write "Apple Global Domain" "AppleEnableSwipeNavigateWithScrolls" '1'

And setting swipe navigation to two-finger-only sets these variables, but perhaps Firefox is ignoring them.

defaults write "com.apple.driver.AppleBluetoothMultitouch.trackpad" "TrackpadThreeFingerHorizSwipeGesture" '0'
defaults write "com.apple.driver.AppleBluetoothMultitouch.trackpad" "TrackpadThreeFingerVertSwipeGesture" '0'
defaults write "com.apple.AppleMultitouchTrackpad" "TrackpadThreeFingerVertSwipeGesture" '0'
defaults write "com.apple.AppleMultitouchTrackpad" "TrackpadThreeFingerHorizSwipeGesture" '0'

So fixing this probably requires a change to Firefox.

I have all options in "More Gestures" disabled:

For experimentation, I tried

• to enabled the option "swipe between full screen apps" with three fingers in system preferences and this will work in firefox.
• also tried with the MagicPrefs app and this allows to remap three finger swipes with firefox (but I would hate to go back to MagicPrefs as jitouch is much better at picking up gestures)

I found the culprit, Firefox is excluded from the three-finger swipe, probably because it has that gesture built in, so we might get double gestures otherwise. Not sure what the best way is to make that configurable.

@aaronkollasch Thank you so much for looking into this! I guess I'll have to train myself to use some other gesture...

[samcarter]

@aaronkollasch Thanks again for digging up the relevant code lines. I've now build a custom version from source without the if-cases and now jitouch also works fabulously with firefox for me! Thank you for your work on this project - this makes my life and probably the life of many other users so much easier!

No problem, I'm glad to hear you got it working for you!

Does it work with Safari too? Or only with Firefox?

[samcarter]

@EugeneTarasenko Yes, it works in Safari, too.
