Starting state
What are users migrating from?
Mobile web share/copy works broadly, but a subset of users replies from mobile browser sessions and wants less context copying or better visible page capture.
Migration path
Mobile web to browser extension fallback migration
A mobile web to browser extension fallback migration should happen only when users show meaningful Safari iOS or Firefox Android browser-first replying. The migration should keep mobile web share/copy as the broad fallback, use visible page context with clear permission copy, support selected copy when insertion is limited, and avoid claiming to solve native app composer workflows.

Target state
What should the migration produce?
Browser-first users can use Safari iOS or Firefox Android extension support where feasible, while native app users remain on mobile web, keyboard, or share patterns.
Migration steps
How should the workflow move?
Step 1
Measure browser-first usage
Identify users who reply from Safari iOS or Firefox Android browser sessions rather than native social apps.
Step 2
Validate context capture
Test whether visible page context can be captured or transferred reliably enough for useful draft generation.
Step 3
Keep copy fallback
Offer selected copy when browser APIs or page structure limit insertion.
Step 4
Document browser differences
Evaluate Safari iOS and Firefox Android separately instead of reusing desktop Chrome assumptions.
Step 5
Limit claims
Position browser extensions as browser-session support, not native mobile app composer support.
Risk controls
What can go wrong, and how should it be controlled?
Wrong segment
The extension may serve browser users while most demand is native app replying.
Require browser-first usage evidence before migration.
Permission overreach
Page access can feel broad without a clear visible-context job.
Explain the exact context capture purpose and keep fallback paths.
Capability overpromise
Insertion may not work reliably across mobile browser pages.
State limitations and preserve selected copy fallback.
Success criteria
How do we know the migration worked?
Segment exists
A meaningful group replies from mobile browser sessions.
Context capture is reliable
The extension can obtain enough visible context for useful replies.
Fallback completes replies
Users can still finish the workflow through selected copy when insertion fails.
Maintenance is justified
Browser-specific review, QA, and support cost matches the segment size.
Fallback plan
What should happen if the migration is not ready?
If browser usage is small
Keep users on mobile web share/copy and avoid extension maintenance.
If context capture is unreliable
Use explicit paste/share context instead of broad page access.
If insertion is blocked
Use selected copy and manual posting rather than forcing a fragile insertion path.

FAQ
Migration questions
When should mobile web migrate to browser extension fallback?
Only after users show meaningful Safari iOS or Firefox Android browser-first replying.
Do browser extensions replace mobile web?
No. Mobile web stays the broad fallback, while extensions help browser sessions where context capture is feasible.
Do browser extensions solve native app composers?
No. Browser extensions should not be described as solving native X, Reddit, or Facebook app composers.
