OMG! Why would Mozilla kill extensions on mobile (android)? It would make mobile unusable for me. In fact that's the reason I barely browse the internet on my iPad: Firefox never had add ons on iOS due to Apple restrictions. I hope that's just FUD!
It's more nuanced than that. Iirc they're rewriting the way extensions are handled internally on Firefox for Android, making only certain extensions available initially. Feel free to look more into it for more precise information, this is all public.
This update will initially include support for one of the most popular extensions on Android, uBlock Origin. Additional extensions will be supported in subsequent releases so you can customize and expand your mobile browsing experience even more."
Why has Moz turned in to this almost fascist company all of a sudden. Like, what? Kill all but whitelisted extensions, which users asked for that?
Let me guess, there'll be an accidental reset of people's config to enable them to be auto-updated and then there extensions will stop working ... I wouldn't put it passed then to then have already secured control over uBlock and we'll have unlockable ads before you know it.
IIRC, this is happening because of the complete internal rewrite - the relevant APIs to expose to extensions simply don't exist yet, and they're implementing them to get the most-wanted extensions available first.
They could use better messaging on this so people who are on firefox precisely for this reason don't think that something has fundamentally changed.
A statement along the lines of "We're working with the most popular Extension creators to get up to speed on the mobile extension API" (which could mean anything) would have been better.
