Feature Request: Toolbar gestures similar to iOS Safari

[dalesnail]

Now that bottom justified toolbar is a thing on mobile, I think further expanding the gesture features in a similar way to safari would be a huge benefit. One example would be holding then swiping up on the toolbar could bring up the tabs list/grid. And another one I use daily and constantly is swiping between tabs this way (just grab it and swipe left/right).

I also think this would bring new users over to Firefox on iOS instead of safari, since honestly now that the toolbar is bottom justified the gestures are the only thing tying me and most people who I've chatted with who were looking forward to this change to Safari (especially since FF Sync is much better for those who also use windows PCs as well as Mac).

This is the biggest thing holding me back from using Firefox on iOS

Which is itself a duplicate of #6326.
