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.
What sucks (IMO) about having to use Agent Spoofers is that it seems like a positive feedback loop for sites to keep making stuff based on Chromium. If traffic metrics basically all show up as Chromium, then they would see less reasons to bother being usable by Firefox or even Safari. Kind of like when the top brass of a company are surrounded by "yes men". But I know it isn't quite that level of bad atm. Though ad companies would more than likely rather deal with working with Google as opposed to allowing Firefox users to keep blocking things.
