I can't speak for the other 25%, but this is certainly true for me. I stopped using the official Firefox when they decided to throw away the entire plug-in ecosystem and moved to Quantum or whatever. After they did, it's been a long, but very stable slide down in power user functionality and what made it Firefox.
