I'd call this a feature :P

Since this is not a regression (and it actually looks better than the other platforms), I'm not sure if we ever want to fix it. According to Markus, the new addon install flow will do away with the stacked doorhangers anyway.

Philipp/Markus: We're thinking that this still has a workaround (dismissing the one prompt before the other) and should therefore be lower priority or wontfix, but what is the expected behavior?

I agree.

The behaviour looks good to me. It displays the most recent doorhanger. I expect the re-install will re-appear once the other one is dismissed.

Overall we would like to get away from stacking doorhangers and instead always display the most recent.
A next version will make the install prompt modal, and add-ons that require a restart will become less. Therefor there should be less and less ways to make doorhangers stack or overlay each other. Which is where we would like to be.
