I don't mind at all if Firefox wanted to propose a standard way to declare cross site sharing, and then allows the user to overrule my settings as a dev (or even if they pick more restrictive defaults, if user opt in is a problem). There's a standard in place, so arbitrary exceptions and heuristics don't create incredible headaches, and there's a clear path to resolving the issue in support/triage with the customer if they create a rule that does actually break my site's functionality. I do mind, quite a bit, when Firefox essentially goes "Fuck the standards", and starts playing fast and loose with the rules. And I mind for two reasons 1. I expect better from them. I'm old enough to remember how much steam Firefox picked up from IE by just treating a standard as a standard. It was novel, and transformed front-end development in a great way. 2. They are not the market leader, and non-standard, site breaking bullshit only does more to sink their ship, and I desperately want a competitor in the browser ecosystem that is not Google Chrome (or a rebranded chromium port).
