Here's a POV, and it's important to note that in general most users don't care (or even know) what their default browser is. At this point in time there are five "major" operating systems with the following global market shares [0]:

Android 35%
Windows 30%
iOS 17%
macOS 9%
Linux 1.5%

If we can agree that most users (not being technically literate, interested or inclined) will not change their default browser, we can easily see why Firefox is losing market share. Basically 91% of the world is - by default - using a non Firefox browser. If their current one is working well enough, why should they care to change it? Can we blame Mozilla for losing some users? Yeah, maybe a few. But that's not really the whole picture.

Edit: I should point out there's a 6.6% group marked as "unknown" in the OS market share data - I left this out to keep things simple.

The statcounter web page uses data coming from trackers blocked by Firefox ETP, radar.cloudflare.com is more accurate.

No, I don't agree. The loss was net, I mean 50M users migrated, the same users that before installed FF over the default browser. Something happened there.

Can we blame Mozilla for losing some users? Yeah, maybe a few. But that’s not really the whole picture.

50M (and counting) was 20% of their user base, not "some users". There's nothing wrong in admitting that Mozilla erratic development model has alienated at least some of "us" (by the way, I've been a FF user for almost 20 years before leaving). And, personally, I'll make whatever I can to make more users leave FF. Fuck Mozilla, really. They're just a cash-grab machine right now.
