Before Quantum everything worked fine. After the Quantum update the touchscreen functionalities on my Surface Por 4 (touch and pen touch both) don't work at all. I waited all this months for a fixing update, but nothing changed so far. Every time I need to use touch functionalities on my Surface I simply switch to a different browser. I am a little bit bored to do so now, so I want to know why there's this annoying problem with Quantum and why Mozilla didn't fix it yet. I already tried to apply this solution, but it doesn't work at all for me: https://support.mozilla.org/en-US/questions/1185899 What happen: Everytime I try to open or close a new window or I touch an icon from a blank page in the top sites, Firefox freeze until I come back to use mouse and keyboard or until I touch the Windows taskbar (that's really weird). Someone else has this problem?
