You're not wrong, even if it is an unpopular opinion. It's really sad to me as an early internet user. Their side projects have all seemed to fail, and Firefox has never been further behind. I don't see them as being solvent in as little as a few years.
That's too harsh IMO. FF is working absolutely great on my desktops, phone, and as dev browser. And Rust seems extremely popular with a vocal minority on HN at least. But yeah, I'm concerned as well - Mozilla should focus on producing a good browser rather than pouring energy into side projects such as Rust and especially WASM which do not contribute to that goal.
Idk about firefox, but MDN web docs is somehow the only online reference for js that's usable (other than the ecmascript specification which isn't for quick learning so much as a deep dive into technical details).
I want to believe that, and even tried to go all Firefox for the previous two weeks. I will say they have good Sync, which nobody outside of Chrome had achieved at all. The desktop browser is mostly OK, no real complaints. On mobile, however, Firefox is noticeably slower than any of the usual blink based browsers, and most importantly to me, uses way more battery life. I love PL things and am glad Rust exists, but from the outside it feels like a wasted effort, for now.
You speak as if FF was a niche product that is a sacrifice to use. There are markets such as Germany, that were always more seceptical of IE/Chrome where FF is still in second place at around 25% and recently rising again while Chrome has fallen back below 50%.
Chrome is definitely the dominant browser, FF is far from irrelevant.
I also echo the content of the sibling comment: on mobile u block origin is really a God send.
That's what I'd been trying. But I've found that Brave and even Opera (issues aside) do it better, and at a fraction of battery life. On my phone battery is king, so I really wish that part were fixed.
I experience the exact opposite on mobile, because it's possible to enable tracking protection which makes 99% of websites I visit more usable, performant, and battery efficient.
