I can reproduce this issue on iOS 10b8 on my iPhone, but not on my iPad.

After some exploration, it seems that this doesn't happen all of the time. Sometimes it shows double prompt, sometimes it doesn't so it may in fact be an issue on both the iPad and potentially iOS9 devices. Unfortunately I had to update the only touch ID device I had to iOS 10 to work on this issue. Simon do you mind testing this on an iOS 9 device with touch ID? Since the issue is intermittent it might take a few back and forths in order to get the double prompt.

Tested on iPad Air 2 - iOS v9.3.3

I managed to reproduced the double prompt issue several times but with no luck of finding reliable steps to reproduce. It mostly occurred when accessing logins after Firefox was backgrounded and restored. 

Also noticed a strange behavior that might be related. When tapping on the login quickly the Touch ID promt will be displayed again. See video: https://www.youtube.com/watch?v=CnzPOWsYZ5U&feature=youtu.be

I am unable to reproduce this in master c63f81b17 (8.0). Is this also fixed in 7.0?

Yes it should be. We had a PR for this a long time ago.
