Updated data for Orange.fr’s new desktop webmail
Orange.fr is currently rolling out a new desktop webmail. And I am afraid it is not a good news.
Out of the 179 HTML and CSS features tested, the new webmail only supports 95 features (from previously 156). In our Email Client Support Scoreboard, Orange.fr’s desktop webmail is falling from the 6th position to the 25th position.
Among the most glaring regressions are CSS properties like background longhand properties (background-image, background-cover, …), border-radius, display:flex or CSS units (like rem, vw or vh). And it also filters out the !important keyword, making responsive emails harder to build. The webmail also drops support for responsive images with <picture> or srcset. And it also no longer supports a lot of accessibility related HTML attributes (like lang, role or any aria attribute).
Here’s a full comparison of the old webmail versus the new webmail.
