UI people seem to start with the idea that they're right and the user should just suck it up, because they went to school and learned words like "skeumorphic."

UI people seem to start with the idea that they're right and the user should just suck it up, because they went to school and learned words like "skeumorphic." This is apparently sufficient for middle management, despite the fact that when this trend of constant annoying pointless changes started, so did the decline of Firefox's user base. I don't even install it by rote on new computers anymore - it might as well be Edge. The rendering performance sucks, the need to constantly adapt to new ui changes is infuriating, so buh-bye Firefox. I prefer software that doesn't screw with my muscle memory for absolutely zero good reasons. UI as a "discipline" is cargo cult corporate waste. I'd rather use a tool designed by an engineer that uses it than performance art disguised as ergonomics or accessibility. If it looks good, fine, but the point of a browser isn't pretty tabs, it's navigating content in a way that doesn't interfere with navigating content.
