Hello, I have problems to login into the Firefox-Sync process. After the last update I have a yellow line at the bottom of the browser window that states that there is a sync problem and that the password would be invalid. After pressing the buttom "Preferences" I can go to the preferences panel, but after clicking the "login" button, I only get an empty page (see attached figure, where I have collected the three screenshots of this process). My system is a Mac with OSX 10.9.5, Firefox is 41.0, I tested with running but disabled Noscript plugin. Any idea how I can reactive the login? BTW: the login data have not changed. I can still login on the sync-sebsite at https://accounts.firefox.com Thanks! Norbert
