The big one is anything to do with video calling — things often work but not as well, or you can voice call but not use video, or something like that. Most of the time the call works well enough, or I use a native app anyway, in which case this isn't a problem, but I suspect this is the thing people are most likely to run into in practice.
The other one is WebUSB, which is useful for certain tools that flash hardware (e.g. keyboards) from the browser. This is rarer, but I still have Chrome around so I can still use these tools. And mostly there's another option anyway, it's just that WebUSB makes things more convenient.
I have heard people complain about Cloudflare, but I've never noticed this. I suspect this is less to do with Chrome/Firefox, and more to do with privacy settings that Firefox makes more accessible. But again, I've never had an issue with Cloudflare myself, so I can't say much about this.
Other than that, I genuinely can't think of the last time I wanted to use a website but couldn't because of Firefox. And even in the above situations, it's rare that I actually run into issues, it's just something I'm aware of as a possible cause if something happens. Most of the time things work perfectly well.
This is an anecdote without a denominator nor a representative sampling.
So if you want it to be relevant, you actually do have to use it. Otherwise you can just as well give up and not care at all about the browser monopoly.
A Phoenix, if you will...
I think the last major scandal was AI additions (cuz who is using AI these days? What an awful idea!) that you can now turn off with one click? Personally never saw the AI features presented to me once. Then the one before that I can remember was the Mr. Robot thing that was so long ago it's hard to remember what even happened. I think they installed a add-on that wasn't enabled and did absolutely nothing unless you went looking for it and specifically wanted it to do something? And then they removed it very soon after when nerds overreacted so hard that we're still talking about it 10+ years later?
Chrome: inability to block ads, new "cookie free" (nope they didn't get rid of cookies) ad tracking, monitoring people in incognito mode, the list would goes on for a long while. Brave: Crypto nonsense, all kinds of advertising for their crap everywhere unless you go through many hoops to turn it off. Firefox is one of the few pieces of software I can say hasn't enshitified itself to the point of using something else.
To add to this, how do I turn off all the AI nagging crap in Chrome?
So it still seems like Firefox is the better option.
I started using Phoenix at version 0.3 (compiling the port on my FreeBSD then-daily-driver) and still use Firefox (and Tor Browser) today. I'm not sure what problem(s) people have with it, but it works for me.
(I also use Safari on my Apple systems, to further diversify web browser usage.)
I am apparently getting too old for whatever that threshold is these days.
If you don’t care about browser diversity, and choose to use a Chrome-based browser, that’s part of the collective’s decision. There are literally billions of people just like you, which is why Chrome wins.
You’re trying to act put-upon, but you’re actually supporting the dominant monopoly side. Your apathy is winning, why do you still feel the need to comment? A bit of guilt or cognitive dissonance, perhaps?
