Re: Could they pick a better example than Firefox?
I am still using Yahoo! mail, and update my OSes - including Mint - regularly, thank you very much.
In the 20+ years I've used Yahoo mail, I never once had a problem. And most pleasingly I can still pretty much use the same interface and workflow to compose an email as I have done two decades ago.
Is Yahoo! modern, sexy, cutting edge - no! no! no!
Is it perfectly and consistently serviceable at what it does - absolutely.
