Full-screen browsing makes viewport to jump up and down when scrolling [SEE VIDEO]
as said on title, whenever the Full-screen browsing is enabled, the viewport will jump up and down. This is: when the user scolls down the page (moving away from the top of the website), the Firefox toolbar (URL bar + menu dots) hides upwards, and the viewport makes a sudden downward jump of the same length of the toolbar´s height. At this time you can continue to scroll normally, raise your finger, interact with something else, zoom in or out, etc, and scroll more as far as you go in that direction. Whenever you scroll in the opposite direction, lets say upwards (so going back to the top of the website), the firefox toolbar scrolls down visible again, but as soon you lift the finger, the screen will jump back again in the opposite direction... so its the same bad behavior but with the reciprocate effect... i attached a screen record to point this up. finger taps are shown on the screen. the page in this case is just a picture from facebook viewed in full size mode, but this bug can shown up with every page available. in the case shown the page was zoomed in and out to show that the behavior is present regardless of zoom state or horizontal scroll. I hope the devs could find and solve this minor bug, love so much this proyect!!
