In fairness, FF will also upgrade to support Manifest V3. The difference is that it will also keep support for V2.
I hope that ad blocking features are eventually seen as a killer feature, driving Firefox market shares up at the expense of “you can’t even block a fucking ad!” Chrome-based browsers.
If that’s gonna happen or not, I have no idea. It depends on how well each side plays its cards. The worst case scenario is Google boiling frogs (i.e. removing capabilities little by little) while Mozilla fails to advertise Firefox in this regard.
Seems like Firefox has already started the marketing campaign targeting this aspect of things. Just be sure to implement a User Agent Spoofer so FF can get around issues revolving around not being chromium based ie specific aspects of webpages tend to be designed only for chromium based browsers.
