Since this morning, the "swipe between pages" functionality doesn't work anymore on my computer!
Web-browser specific description of the problem
Google Chrome
When I try to swipe between pages on Google Chrome, it just does not work. The window get shifted within its frame and come back to its original position.
Safari
When I try to swipe between pages on Safari, the window slightly shifts within its frame and get stuck into this position. Further two-finger movements (including scrolling up and down) are then not functioning. When I open a new window, the scrolling up/down is working again.
Firefox
When I try to swipe between pages on Firefox, nothing happen and further two-finger movements (including scrolling up and down) are then not functioning. When I open a new window, the scrolling up/down is working again.
How I tried to solve this issue
I opened system preferences to make sure that in the section trackpad, the option swipe between pages is activated. Yes, it is activated!
For some reason, I checked the always box next to Show scroll bars in the general section in the system preferences.
In Bash, I wrote the following command line: defaults write -g com.apple.trackpad.scrollBehavior 2 but nothing happens!
Best Answer
Try logging out and back in.
I know that sounds like a "grasping at straws"-type solution, but this is the sort of doesn't-make-sense kind of problem that I've seen fixed by logging out (or maybe even restarting).
