What? Just fix the ciphers to a list of what's known to work + some safety margin. Each user needing some different specific cipher (like a cipher for horses, and one for dogs), is not a thing.

That's already the case. The trouble is that NSS (what firefox uses) doesn't support the same cipher suites as boringssl (what chrome uses?).
