I have rawengulksans font installed as a font on my website, since the automatic update to 44.0 this font is no longer displayed. I have rolled back to a earlier verison of firefox and the font works fine. I have also tested the webpage on IE, Chrome & Safari these browzers also display the font with no issue. @font-face { font-family: 'rawengulksansregular'; src: url('../fonts/rawengulksans-094-webfont.eot'); src: url('../fonts/rawengulksans-094-webfont.eot?#iefix') format('embedded-opentype'), url('../fonts/rawengulksans-094-webfont.woff2') format('woff2'), url('../fonts/rawengulksans-094-webfont.woff') format('woff'), url('../fonts/rawengulksans-094-webfont.ttf') format('truetype'), url('../fonts/rawengulksans-094-webfont.svg#rawengulksansregular') format('svg'); font-weight: normal; font-style: normal; }
