This question already has an answer here:
When looking at a PDF document I often want to zoom-out to scroll quickly to its contents and get an overview.
However, when I zoom-out past a certain threshold (it seems to differ per PDF) Safari thinks I want to see the tab overview:
I have never found a use for this function, so it only causes annoyance.
Can I turn this tab overview off somehow? A solution that uncouples the pinch-to-zoom gesture from the functionality would also work.
I'm on Mountain Lion 10.8.5 with Safari 6.1.3.
