Linux user here running FF, no real dealbreaker issues at my end.

I use Mozilla every single day and have done so for about 6 years now. Personally I don’t feel like I’m missing out on anything but ads if I don’t a Chromium based browser.

I’ve got plenty of old software here under Linux that still runs fine to this day across a number of PC’s and even a Raspberry Pi that I use as a backup desktop. I honestly can’t see backwards compatibility being any more of an issue than it is under Windows - There’s a number of accounting packages released under Windows 7 that won’t run under Windows 10, the latest version of most popular browsers won’t run under Windows 7. Likewise, the latest version of MS Office 365 won’t run under Windows 8.

My overview transition is seamless running X11.

I find the opposite running KDE Neon. In fact File Explorer ‘lag’ is a widely expressed issue regarding Windows 11.

The possibility does exist. I think the Adobe CC hasn’t been released under Linux for a similar reason, as Microsoft and Apple know that should Linux get the Adobe CC, people will flock to Linux.

A number of years back Adobe accidentally released a slide showing the Adobe CC running under Ubuntu, but strangely the product was never released on the platform.

Which is also the case under Windows. As stated, no OS is immune to driver issues.

No, Windows comes preinstalled on most PC’s due to clever marketing. As stated, it’s more a case of people thinking Windows is the computer as opposed to any form of comfort regarding a fragmented touch/desktop UI making poor use of screen real estate.

I come across a number of Mom and Dad, Grandma and Grandpa types that outright struggle with Windows; the device they feel comfortable with is the iPad.

Fonts look fine here under FF:

Been using FF since forever, never felt my experience was in any way slow compared to Chrome.

I think it’s a Java thing?

I never stopped using Firefox, and I never had a problem with anything but Government sites.

Does EAC work correctly playing Apex Legends under Linux? If it does I’ll download the game tonight.

I haven’t experienced an issue adding PPA’s in about four years. The package manager simply does what it’s meant to do and things just work.
