Since using W10 Webfonts are broken, Firefox Web Console is full of downloadable font: not usable by platform (font-family: "FontAwesome" ............... Internet Explorer Web Console is full of CSS3111: @font-face encountered unknown error Instead of the symbols or icons, a rectangle with very small numbers and letters (e.g. F0D7) is shown, it's quite annoying on many webpages, as you don't know what will happen by clicking on this chinese looking symbol. Furthermore, same happens on the GUI of firefox addons uMatrix and uBlock, rectangles with numers and letters. Seems as if downloadable fonts are restricted / forbidden under Windows 10? Anybody else experiencing this?
