Hello, I'm using Firefox 57 Quantum (x64) on Ubuntu 16.04. Prior to update to 57 i was able to log-in into microsoft services (like portal.azure.com), but since update to 57 i get an error during oauth2 redirection process - page login.microsoft.com/... fails to load (see attached screenshot). I already tried login in Firefox safe-mode (with add-ons disabled), but the result was the same. I also tried clearing cache, cookies and history as suggested in some other threads, but there was no difference.
