Firefox or Alien app closing problem
This may not be a new problem: I used never to close Firefox but since SFOS3 I've been closing it accidentally by swiping down.
If I close Firefox, either by swiping down or on the cover page, it won't start up again cleanly. The main problem is that parts of my addons don't work, though I've noticed other effects - e.g. it doesn't render a recovered tab so you have to delete it.
I have to stop-restart Alien to recover full functionality.
Has anyone else noticed this? Any idea what might cause it? I'd guess it's Alien or the SFOS/Alien interface, not Firefox.
