Use mobile web for first Android validation, Android keyboard for native app UX, and Firefox Android extension as a browser-user add-on.
Workflow decision
Firefox Android extension vs mobile web for AI replies
Mobile web + share/copy should come before Firefox Android extension support because it validates reply demand across native app and browser workflows. Firefox Android extension support is useful later for Android users who browse social sites in Firefox, but it should not replace Android keyboard planning.
