Use this matrix when deciding whether Safari iOS or Firefox Android extension work deserves roadmap priority.
Scoring matrix
Mobile browser extension priority matrix
A mobile browser extension priority matrix should put Safari iOS and Firefox Android extensions after mobile web and native keyboard learning. Mobile browser extensions score high only when users already reply from browser-based social sessions. They should not be the first mobile MVP or a replacement for Android and iOS native composer workflows.

Scores
1 to 5 scoring matrix
| Criterion | Mobile web | Android keyboard | iOS keyboard + Share | Browser extensions | Recommendation |
|---|---|---|---|---|---|
| Browser-first segment fit | 4/5 | 2/5 | 3/5 | 5/5 | Browser extensions win only for users who already reply from mobile browser social pages. |
| Native app reply fit | 3/5 | 5/5 | 4/5 | 2/5 | Native keyboard paths matter more when X app composers are the main workflow. |
| First MVP confidence | 5/5 | 2/5 | 2/5 | 2/5 | Mobile web remains the best first mobile MVP because it validates demand before browser-specific work. |
| Extension maintenance scope | 5/5 | 3/5 | 2/5 | 3/5 | Browser-specific work should wait until segment demand is visible. |
| Fallback usefulness | 5/5 | 4/5 | 4/5 | 5/5 | Extensions can be valuable fallback surfaces after the core roadmap is validated. |
Selection rules
How to choose the winning path
Rule 1
Prioritize mobile web
When the team needs broad mobile proof across app and browser users.
Rule 2
Prioritize Android or iOS native
When most friction appears inside native social app composers.
Rule 3
Prioritize browser extensions
When interviews and analytics show meaningful Safari iOS or Firefox Android social-browser replying.
Rule 4
Keep them as add-ons
Mobile browser extensions should supplement, not replace, the core mobile roadmap.
Risk checks
What can make the matrix lie?
Tiny segment risk
The browser-first mobile audience may be smaller than expected.
Validate with surveys, support tags, and mobile referrer behavior.
Desktop assumption risk
Desktop extension UX may not transfer to mobile browser APIs.
Run separate Safari iOS and Firefox Android feasibility checks.
Native app mismatch
Browser extensions do not solve native app composer insertion.
Keep keyboard and Share Extension paths separate.

Users who reply from social sites in mobile browsers rather than mainly using native social apps.
Do browser extensions replace ReplyPilot Keyboard?
No. Browser extensions help browser sessions, while keyboards help native mobile app composers.
