I'm experiencing issues where trackpad 3 & 4 finger clicks don't work on certain websites. For example, if I set a 4 Finger Click on my trackpad to do a keyboard shortcut of Command W (close window), it won't work on this Adobe website if the cursor is anywhere on the website:
I could only imagine you have some advanced trigger condition or CAG set up that disables the behavior for certain sites. I just tried here and it seems to work fine.
Does pressing cmd+w on your keyboard work for you?
Pressing Command W on my keyboard closes the window. But for some reason, a 4 finger click on my trackpad to trigger a Command W keystroke doesn't work on certain websites. It only fails on a few websites though.
I wish there was a way to permanently block websites from having any control over the functionality of my trackpad.
