Has become worse and less reliable over the years.. The freshly installed version in FF57 allows to select the iconc (under preferences).. I have saved the settings. Nothing changed in FF. Closed the browser, and restarted. Result the old icons are back.
Does anyone actually check the basic working of a released program??
In addition the option 'save email' in the login screen does no longer work either. The email is blank every time I restart FF and go to the login screen (and yes the check mark 'save email' is set).
