Why does Firefox throw an error when downloading a font?

Question

css

I created an icon font, connected it to the page. Firefox throws this error in the console:

downloadable font: download failed (font-family: "untitled-font-1" style:normal weight:normal stretch:normal src index:1): status=2152857618 source: file:///C:/Users/Lenovo/Desktop/csgosite/css/fonts/untitled-font-1.woff
