Mobile chrome (IOS/Android) has a feature where if you swipe at the left or right hand margins of the screen it changes tabs.
My web app uses swiping, and this \"feature
No, there's no way to disable this gesture.
There's a ticket requesting the feature over at https://code.google.com/p/chromium/issues/detail?id=117657 if you want to star it / chime in.
If you use two/multi fingers, the swipe works even from the edge/borders.
