Hi there,

Sorry for the late response. One of the Firefox developers has replied on Reddit. To keep this thread updated, I'll quote their post:

Hi, sorry for the hassle! This is definitely not the expected behavior here! We'll be shipping an update next week that disables the prompt for the time-being while we continue trying to debug why it's popping up so frequently for some users. tempforstanley, would you be willing to connect with one of our Android engineers to try to diagnose what's going on in your case? We've gotten a few reports of people hitting this but haven't been able to nail down the circumstances yet for why.

Thanks for the response! I'll copy my reply here just in case:

I would be willing, but since I've reinstalled the app and the popup is gone, I'm afraid I might not be of much use anymore :( Let me know if there is some way to get archived data, though!
