Firefox tries but this is very hard to fight against. Most of the obvious holes were closed long ago. Now these fuckers use normal browser functionality that can't be disabled and record how it subtly differs (in various ways like execution time of functions) between different combinations of browsers, OSes, hardware, etc. This information alone is enough to create a more or less unique fingerprint.
The only reliable solution is to completely get rid of client-side code execution like JavaScript and WebAssembly and return to static web pages. Which of course won't happen.
