After upgrading to Firefox Daylight, I'm experiencing an issue I saw a long time ago already: I can load and navigate websites for a while, but at some point no page will load any more. The loading progress bar is stuck at about ⅓, and Firefox just does nothing. Navigating back, opening bookmarks or new or old tabs all present the same issue. When I close Firefox by swiping away it's window and restart it, sometimes it fixes the issue, but only for a while. I also tried clearing Cache, which didn't change anything either. Opening the menu and settings works. about: addresses don't seem to work, about:home shows "invalid address". I'm on Android 6, Firefox 81.1.1
