Yahoo mail and many other Yahoo pages display sans CSS coding in new Firefox 47
It started After an update to Firefox 46 with my.yahoo.com losing all personalizations and Yahoo Mail appearing as in the attached image. After updating to 47, the problem remained. I removed all cookies associated with Yahoo and restarted the browser. my.yahoo.com now displays correctly, but Yahoo Mail and all other Yahoo based pages appear as the attached. I removed all add-ons and extensions, and replaced them one at a time, nothing works. This displays correctly in Opera, IE and Maxthon browsers.
