Comment 15 for bug 1377996

@tenleffingers to clarify you can only get the app working again by stopping it and restarting it? if thats the case its not merely a focus issue and sounds like the app itself is hung

We might now try to reflash if you are ok with that.
1 - flash stable channel without a full wipe
2 - if that doesn't clear the issue, back up your user home and flash with --wipe
3 - if that fixes it, restore the user home and see if it stays fixed or reappears
