This honestly sounds like a great idea. At this point I'd pay money for a browser that was private, fast, and dev-friendly, simply to avoid the moral dilemma of switching from FF to a Chrome clone.
It's an honest question, since as a user I really love it. Is it the 'dev-friendly', which Firefox lacks?
After misclicking hundreds of times, I still couldn't train myself to go against my perception and follow the designer's "bold vision", using it feels like writing with my left hand or steering a bicycle with a crooked wheel.
• Profiling functions between Chrome/FF reveals that Chrome is frequently considerably faster (usually 60%+)
• During WebGL work I'll often hit blue screens around memory management (this seems to be a relatively recent development)
• Similarly, trying to profile a WebRTC application with video feeds will consistently trigger a blue screen. (I can tell this is from FF, as the browser itself flashes white a few times before the system goes down.)
• Things like the UI changing - while minor - are enough to cause inconvenience, plus the occasional random feature removal (View Image context menu option) indicates that I'm not necessarily the target audience for the browser.
I actually slightly prefer the devtools in FF than Chrome, but there are a number of quirks that have started appearing over the past year or so, ranging from actual bugs to just weird UX.
As I write this, I'm realizing I'd love a browser that's seen more as a devtool than a catch-all web navigator which happens to have a profiler built in.
What normally happens with native GPU intensive apps is that devs change their code to work around driver and OS crashes, and if the app becomes popular, GPU vendors will react to frequent crashes from that app with driver fixes.
I actually liked the UI they implemented in Android. Alas, I seem to be in a minority
That said:
I'm not salty because they replaced XUL but because they mostly gutted it without replacement.
I'm salty because they pretend we are a community whenever they want donations but write as if we are enemies when we try to ask very nicely about something that is missing and has been missing for years.
I'm also salty because they really haven't been clear about donations not going to browser work but to all kinds of niche projects.
