Swipe up or down on toolbar to reveal tabs in Firefox Android.

This is something Chrome can do that I found pretty useful and convenient. If your toolbar is on top, swipe scroll down to reveal it and then swipe down on the toolbar to reveal open tabs. Likewise if your toolbar is on the bottom swipe up to reveal and up again on the toolbar to reveal the tabs.

Considering the dismissal gesture for the tab window is already a swipe towards the toolbar edge, this seems like a natural extension of that movement.

On the latest Firefox, it seems to work for me now.
