@sabreW4K3 In that case, try switching the tabs to list view from grid view in the settings for tabs. It's not exactly what you're looking for, but it should at least address the problem.

@sabreW4K3 I don't really understand. When scrolling tabs in Firefox in Android it goes from top bottom, but swiping them away is to the side. Do you mean when you want to swipe back using the gesture swiping that it swipes the tab away or is it something else?
