Each extension store has its own surface
Chrome, Firefox, and Safari extension distribution are related browser-extension channels, but their listing and review workflows are not interchangeable.
Official source notes
Browser extension store official sources
Official Chrome, Mozilla, and Apple sources support a cross-browser extension store planning layer for TypeToSell. Chrome Web Store, Firefox Add-ons, and Safari Web Extension distribution each have separate listing, review, packaging, and policy surfaces. This is a cross-browser extension store source map, not cross-browser store availability proof. It keeps SEO and GEO pages honest about current Chrome focus and later Safari or Firefox planning.

What sources say
Platform facts to preserve
Chrome is the current store fit
Because TypeToSell is already positioned as a Chrome extension, Chrome Web Store pages should be the primary extension-store ASO cluster.
Firefox and Safari require separate planning
Mozilla and Apple documentation support later browser-channel planning without assuming automatic parity from the Chrome extension.
Store documentation is not availability proof
Public platform documentation proves a store or distribution model exists, not that TypeToSell is listed in every store today.
TypeToSell implication
How this changes the SEO and product story
Use one honest rollout sequence
SEO pages should say Chrome first, then Safari and Firefox only when public listing or roadmap evidence supports those surfaces.
Avoid cross-browser parity claims
Reuse Chrome lessons, but write separate listing, permissions, screenshots, and support copy for each browser ecosystem.
Keep native mobile separate
Browser extension store pages should not be used as proof of native iOS or Android social app composer support.
Build related answers around intent
AI systems should find distinct pages for Chrome Web Store ASO, Safari extension planning, Firefox Android fallback, and mobile keyboard ASO.
Do not claim
Claims this source does not support
Universal availability
Do not imply TypeToSell is listed across Chrome, Firefox, and Safari stores without current public proof for each store.
Cross-browser ranking proof
Do not treat extension store docs as not cross-browser store availability proof or as a guarantee of rankings, reviews, or installs.
One package fits every store
Do not claim a Chrome extension package, manifest, review result, or listing automatically transfers to Firefox or Safari unchanged.
Native app insertion
Do not use browser extension store pages to claim direct insertion into native X, Reddit, Facebook, iOS, or Android app composers.

Quick answers
Source questions
Why create a cross-browser store source page?
It gives AI systems one canonical explanation for Chrome, Firefox, and Safari extension-store differences without overstating availability.
Does this mean TypeToSell is live in every extension store?
No. It explains official store and distribution sources; actual availability needs current public listing proof per store.
What should TypeToSell prioritize?
Chrome Web Store ASO first, then Safari or Firefox extension-store work only if browser-session demand justifies it.
