Yes it's bad, and I'm not defending Mozilla here with any great enthusiasm, but it could have been worse.
I built a Windows 11 system the other day for someone. Once the clean OS build was sort-of running, I needed to connect to an intranet site to grab various apps, drivers, content etc.
I have a pathological aversion to Edge - for reasons that will become self-explanatory - so I figured I'd fire up IE to do it. It's just an intranet site, static content, nothing fancy, so IE would have been perfectly adequate.
IE loaded. But then - Microsoft having deprecated it "for our own good" - every single URL I entered into it opened up Edge instead.
So far, you're probably thinking "meh, so what, quit your whining, it's not 1998 any more", and to be honest, if that's all it had done I'd probably have swallowed my Edgeaphobia and ploughed ahead.
But no. Edge is the most needy, emotionally stunted browser there is, so every time it was opened from IE, it opened up as a modal, full-screen splash, inviting me to make it my best friend, sign in to my Microsoft account (fuck no), allow it to manage my passwords, feed me the usual homepage celebrity tripe, etc etc.
Thinking this was a one-off, I killed it from Task Manager and tried again. Nope, same behaviour, repeat until the red mist descended. Edge did not want to do basic web browsing until I had made it my BFF and patted it on the head and told it I loved it.
Am I the only person repelled by this? Any application that takes over my entire desktop and blocks further multitasking until I attend to it goes straight onto my boycott list. Windows 10/11 have a vile habit of doing the same thing randomly after booting, again trying to bounce me into using a Microsoft account or whatever. I sympathize with the people quoted in the article; anything like this that breaks my workflow and gets between me and the task I'm trying to do makes me livid.
So... my Edgeaphobia further reinforced, I grumbled and dug out a flash drive with a fairly recent copy of Firefox on it. Firefox might occasionally push a VPN at me (not that I've seen that) or offer me Pocket sponsored stories, but at least those behaviours can be disabled.
(Rant over.)
