Regressed Preloaded stylesheets are not applied to the page

Published: | Categories: CSS


Firefox 56 has added the support for preloading content with <link rel="preload"> for a better web performance. However, there have been reports of preloaded CSS stylesheets not applied to the HTML document properly. For that reason, this new feature will be temporarily disabled in Firefox 57 while Mozilla developers are working on the solution, and is planned to be re-enabled with Firefox 58 coming January 2018.
