I don't think workflow concerns can just be brushed off. Breaking changes and constant design churn is devastating for user retention.
What users want is a working browser that gets out of the way and them browse the web. That's what Chrom(e,ium) is. It's like air, it's everywhere but you can't see it.
Firefox is not. Every time you open Firefox, there's a new dialog announcing some change or shilling some product. It's cut from the same cloth as that car that Homer Simpson designed. Every time you open Firefox, it works a bit differently, so you have to unlearn some habit and learn a new one[1]. This is friction. This grates. You have some task to perform, which is why you opened the browser, but now you your blood pressure is up 20 points because firefox can't just let you browse, it's always telling you stuff in a dozen different channels, popups, toasts, notifications, there's always something it throws in your face, often multiple calls to action at once. So you say for fucks sake, and go back to chrome which just lets you browse with none of that nonsense.
These are all the calls to action I get when I open firefox. Which I opened yesterday as well, so it's not a clean install.

Why is there a dialog announcing widgets, when I can see the widgets already? It's literally telling me what I see on the screen. Why do you need this exposition to inform me of something that is plain to see in front of my eyes? It's like bad fiction writing, except in the form of annoying UX.
Like is anyone working on Firefox actually using the browser, in its vanilla configuration? How can they not see how infuriating it is to be a Firefox user?
[1] 5 years ago we changed which kitchen drawer we keep the cutlery in, and I still reach for the wrong one every time.
Yeah, definitely agree with this. I still use Firefox a bit on some machines but it is constantly popping up little things - "are you finding tabs overwhelming? try tab groups" / "try vertical tabs" / whatever. I'm not finding them overwhelming, just shut up please.
Also the context menus are super noisy, I tried cutting some bits out in config, but there's just so much crap in there. Obviously all the AI stuff, but also just the basics; right-clicking on a tab has a sub-menu for "Close Multiple Tabs" which hides "Close other tabs" and "Close tabs to the right" which are probably what I use the most. In Chromium they're top-level menu items.
And it went through a phase a few months ago where the context menus were sometimes offset or goofily sized; I think that's fixed now.
I guess it's easy to criticise, but it just doesn't feel like this stuff is well aligned to actually using the browser, whereas Chromium feels like a solid product.
