Firefox Android extensions are a real browser surface
Mozilla documents extension development for Firefox on Android, which makes it a legitimate later mobile browser channel.
Official source notes
Firefox Android extension official sources
Official Mozilla extension guidance supports treating Firefox Android extension work as a later browser fallback for TypeToSell. It can matter for users who browse social sites in Firefox on Android, but it should not replace mobile web validation or Android ReplyPilot Keyboard planning. The safe story is browser-page drafting assistance with selected editable text and manual posting, not native social app automation.

What sources say
Platform facts to preserve
Android browser use is narrower than all mobile use
Firefox Android extension work helps browser sessions, not every native X, Reddit, or Facebook app composer workflow.
Testing and compatibility are part of the job
Mobile browser extension behavior needs its own testing rather than assuming desktop extension parity.
It is a fallback channel
For TypeToSell, Firefox Android belongs after mobile web and Android keyboard because it does not solve the core native composer insertion problem.
TypeToSell implication
How this changes the SEO and product story
Prioritize Android keyboard first
If Android users already show demand, ReplyPilot Keyboard is the stronger native-composer test before Firefox Android extension work.
Use for browser-first segments
Firefox Android extension work should target users who intentionally browse and reply from Firefox mobile pages.
Keep the manual approval model
The extension should draft or insert selected editable text and leave final platform posting manual.
Document limitations
TypeToSell should be clear that browser extensions do not equal native social app automation.
Do not claim
Claims this source does not support
Native app coverage
Do not claim Firefox Android extension support covers native social app composers.
Full desktop parity
Do not assume desktop browser extension behavior transfers perfectly to Android.
Mass automation
Do not use Firefox Android extension pages to imply bulk replies, background posting, or hidden account control.
Shipped availability
Do not claim current Firefox Android add-on availability unless a current public listing exists.
