> Your post is a load of mimimization of my concerns, and redirection about how I couldnt possibly comprehend these complexities.

I apologize. That was not my intention. Being ESL may played into how I expressed my opinion.
Again, apologies!

> What i care about is my experience as a user is being objectively destroyed by these kinds of changes, go on and call me a "loud minority" or say "our metrics indicate [ ... ]". The fact remains that those are dismissive statements that indicate that you really don't care about these issues, so please stop insulting me by pretending you do.

I certainly didn't mean to insult you. I apologize if that's how it feels.
Being a minority doesn't mean you're "wrong" or "irrelevant". I consider myself a vast minority (I use Linux, I'm a software engineer, I'm a Pole - all those are minorities!) and it certainly makes what I need from software, different than what most people need from software.

Understanding that I'm a minority helps me understand why what I want may not be the best for a product like Firefox.
I genuinely would want Firefox to add client side decorations (being worked on in bug 1283299) before they add color accents for Windows 10 (which I don't use).
But understanding that I'm a minority helps me understand why the priorities of Firefox UI module owners are different.

I don't want to be dismissive, just point out why what you or I want or believe is right, may not always be the best from the perspective of someone who has to decide for the product used by hundreds of millions of users.

> It dosent mean that its acceptable to me as a user who is being essentially told we dont care about your use case anymore.

I agree that what matters for you as a user is the outcome. I don't expect you to be happy about the decision that doesn't give you what you need because of the fact that "it's the right decision" on some other level.

But I ask you to separate your wants and needs as a user from indicating that decision makers are wrong in their decisions when they go against your needs.

And I also disagree that not doing what you want equals "not caring about your use case".
It's not about "care vs. not care". It's about priorities.

If your use case is valid, but not common, it will most likely just wait longer to be fixed (like CSD). If the value of what you ask for is going to bring less value to fewer users than the opposite, then the right decision for the decision maker is to do the opposite. Not because "they don't care", but because there's a more substantial value in it for more people.

> Please try to understand that mozilla are essentially taking everything that I gain utilty from with firefox, and tossing it in the dumpster.

I do understand that. I'm very sad to hear that this is what is happening to you, and I understand your frustration.

Please, try to understand that:
a) I'm not a decision maker, so I can only share my perspective.
b) Even if I was, I would probably have to see the bigger picture and may have to make the same decision.

> Don't expect me to not be upset

I don't. I really don't. I understand you're upset and I believe you have the right to be.
I just ask you to separate being upset, and making decisions based on it, from accusing others of not caring for it is possible to care about your use case, and yet make the rational and valid decision against it based on the value for more use cases.

I believe we're dropping into philosophical conversation about decision making that is getting close to trolley dilemma :)

> For what its worth I think you will find this "loud minority" is more influential than your metrics capture, and post 56 you are going to see a lot more people moving to chrome.

I can't argue here, only trade opinions. I hope that the technical value of the product will make it a good choice for more users than use Firefox today, and that our investment in improving the extension ecosystem will result in replacement for all the features that you miss today.

I know I'll work on that within of what I can do.
