I find this notion completely baffling. I use Chrome, Firefox and Safari more or less daily cause I test in all 3, and other than Safari feeling clunkier and in general less power-user friendly, I can barely tell the difference between the 3, especially between chrome and FF (well, other than uBlock working better in FF anyways).
Whole portions of the Verizon website, for example. Or the website of a well known kindergarden I was researching recently.
I think it's a case of yes, it does work, but web developers don't think so, so they implement checks just for kicks.

I am baffled by the choice to include this laughably obscure example alongside a major telecom. Surely there are better options less likely to be the fault of a random lazy web developer.
Youtube, for example seems deliberately hampered on non-chrome browsers.
It isn't unique to youtube either. Gmail offline mode only works on chrome, even though other browsers have the necessary APIs. And menu copy and paste in google docs uses a special chrome-only extension that google pre-installs in chrome, instead of the clipboard API that works in other browsers as well.
I made some other changes, but I forget what. At least FF still has the full uBlock Origin.
Except the YouTube thing but that's because I'm not even sure what you're talking about: I leave YouTube windows open in Firefox for weeks.
It occurs to me that it could be a pathological edge case triggered by ublock and youtube interacting. I'm not going to disable it to find out.
I didn't, for decades, but it was a mistake.
News to me.
If this is even true, in the end it's still "so what?" Meaning, the alternative is even worse so, let's say granted there is this problem. Where is the better alternative that does not have this problem? Chrome doesn't have other equivalent or worse memory problems? Even if not leaking, it simply uses so much it's the same end result.
I've never consciously noticed a problem with youtube so if there is a problem, it's not one that necessarily matters.
