Autofill works in Firefox but not Fennec

Hi @refi64, I'd be happy to clarify how 1Password identifies browsers...

We store a list of known browsers within 1Password that identifies apps by a combination of their package name and signature. Any apps that are included in that list are treated as browsers (as in 1Password attempts to determine the URL of the web page), otherwise they are treated as regular apps.

We're somewhat careful about which browsers we add to this list as each browser we add requires additional testing and maintenance to ensure that it works well with both the Autofill and Accessibility frameworks in Android. At the moment, the list includes versions of Chrome, Firefox, Opera, Microsoft Edge, Samsung Internet, Brave, Duck Duck Go, and Vivaldi. Since this list doesn't include Fennec, it is treated as an app rather than a browser.

I hope that explanation helps to clarify the behaviour that you're seeing!
