I'm using Firefox 77.0.1 In earlier versions of Firefox, the password needed for a local log-on to an ip address was auto filled. Unfortunately with the latest version it needs me to manually enter the user name and password every time. I've tried editing the Firefox about:config where a previous suggestion was to change the "signon.autofillForms.http" to "True", the local web address in question is http://172.20.10.9 and may therefore be regarded as insecure. Microsoft Edge has no issue with saving and using the user name and password. Thanks
