This looks like they're not so much launching a paid version of Firefox-the-browser, but a paid subscription service, including e.g. a VPN service. This is in line with their recent push towards Firefox as a brand for related services and products like Firefox Send and Lockwise in general, with the browser being specifically referred to as Firefox Browser. So presumably, Firefox accounts will become a freemium servic…
For that however, many things (which are far from trivial) have to be done. Among other things:
1. Focus on security. That means among other things:
1a: Reducing core code complexity (for example, removing Pocket and integrating it only as an opt-in extension)
1b: More audits
1c: More Rust (and Servo by that extension)
2. Focus on integrating more privacy-enhancing features, such as:
2a: Reducing the effectiveness of browser fingerprinting
2b: Integrating more features from Tor-Browser into vanilla Firefox. Would be even better if they integrated Tor out of the box too.
In fact, Firefox should perhaps aim at 0 difference between TBB and vanilla Firefox.
2c: Reducing reliance on (user-hostile) search engines. Perhaps integrate DuckDuckGo as default search engine in the future?
3. Focus on marketing campaign which includes super noob-friendly (video) tutorials. I'm thinking something in the Kurzgesagt style.
