Got any concrete examples? I hear this a lot, but have never experienced it. I’ve been using Firefox as my primary desktop browser for years now. I can’t think of any website that didn’t function. But maybe I encountered one and just thought the site was down?
In my case: several financial institutions that I have accounts with and lots of enterprise apps and gear with web UIs either break silently, have certain functions that don't work, or block with an error telling you to use a supported browser. (If they're nice, they even tell you which ones are supported.)
For a while, Slack didn't support all features on Firefox despite the technology being there, I don't know if this is still the case.
More than once I have spent precious time filling out some form or going through some wizard only to find that I cannot “submit” or that validation is failing on some field or other in Firefox. Switching to a Chromium based browser works. I know it has happened to me at my bank. I cannot recall exactly where else. Reservation systems? A couple of travel approval sites I think ( during COVID ).
The Hebrew language Nespresso site pops up a browser dialogue "you have unsaved changes" every time one tries to browse to another page. The dev team is aware of it, but "the site only supports Google Chrome" so they don't fix it.

The version of Unit 4 that we use at work only works in Chrome.
That said, lately, that particular thing has been the only one that I need to use that outright doesn't work.
I think a number of Google technologies are slower in Firefox on purpose, but I just avoid them and keep telling competition authorities about their abuse of power.
Reading that thread, it sounded like OPs issue was more with an extension blocking something than the browser, but I’ll admit, I do not use GoDaddy, so I haven’t experienced it first hand.
