Mobile browser extension requirements

Mobile browser extension requirements for Safari iOS and Firefox Android should come after mobile web, Android keyboard, and iOS keyboard plus Share Extension validation. They should serve browser-first social reply users, prove context capture feasibility, keep copy fallback when insertion is limited, and avoid pretending to solve native app composer workflows.

Product goal

What should this requirement set accomplish?

Support users who prefer mobile browser social sessions without confusing browser extension work with native app keyboard or Share Extension workflows.

Functional requirements

What must the product do?

Browser-first detection

The team can identify users who reply from Safari iOS or Firefox Android browser sessions.

Visible page context

The extension can capture or help transfer enough visible page context to draft useful replies.

Copy or insertion path

The browser flow supports selected draft copy or insertion depending on platform capability.

Mobile web fallback

Users can fall back to mobile web share/copy when extension APIs are limited.

Acceptance criteria

What must be true before this is ready?

Criterion 1

Segment is real

Support requests, interviews, or analytics show meaningful browser-first mobile replying.

Criterion 2

Native app mismatch is stated

The page explains that browser extensions do not replace native app keyboard workflows.

Criterion 3

Permission story is clear

Users understand why a browser extension needs page access.

Criterion 4

Manual final posting remains

The user reviews, edits, and manually publishes the final social reply.

Non-functional requirements

What quality bars must hold?

Browser-specific feasibility

Safari iOS and Firefox Android behavior should be evaluated separately, not copied from desktop Chrome assumptions.

Maintenance control

Do not add browser-specific support until the segment justifies ongoing QA and review work.

Roadmap honesty

Unshipped browser extensions should be labeled as evaluation or roadmap items.

Safety parity

Browser extension copy should match TypeToSell's no social password and no auto-posting promise.

Out of scope

What should not be built or claimed?

First mobile MVP

Mobile browser extensions should not replace the mobile web share/copy MVP.

Native composer replacement

Browser extensions should not be described as solving native X app composer insertion.

Automatic posting

The extension should not submit social replies on behalf of the user.
