Why doesn't font-weight work in Firefox?

Question

css

Subject. I have noticed for a long time that font-weight does not work in the muffin, at least for local fonts. And no, the styles are not interrupted by anything. Other browsers are fine. I myself always use muffin during development, I have already lost the habit of using font-weight, but today this particular case has appeared. Here it became interesting. In another browser (Chrome, Vivaldi, etc.), I look through the inspector which value I like best - 100,200,300, and so on. In mazil up to 700 everything is the same, and 700 is already = bold. In this case, I need to specify 500, I indicated that it works everywhere, the same thin font is in the muffin. And no, the problem is not in the muzzle, this problem has been around for many years, during this time I have already managed to reinstall Windows 5 times, and as a result, the browser.
