Auth tab on mobile causes game to relaunch

On Android, when I open the game and click online it opens Firefox to perform discord authentication. This part is fine, but when I am done playing and go back to Firefox, the tab that auths with discord is still open, and triggers the game to start running again. This happens because it is always going to be the most recently opened tab, so it will be the tab you return to when reopening firefox. I suggest that maybe the tab should close on its own after finishing authentication, if that is possible. Or after it authenticates it should redirect to something else. Or perhaps omega could open the mobile browser in line, like how other apps like discord/twitter/Facebook can use default android chrome to follow links without opening the browser “for real”.
