My desktop computer has somehow lost all its settings. Not sure we properly backed everything up. If that is bad enough I cant make Mozilla Firefox my default browser. I click on the options setting (upper right) then make Firefox the default, then go to "Default Apps" under the computer main settings, Firefox does not show up as an option. If this makes any difference I also have Microsoft Edge (new version) installed, and so Microsoft Edge and Google Chrome show up as options but not Mozilla. Additionally, every time I restart my computer I have to log back into Mozilla and have lost all my settings! How do I make it so that Mozilla shows up as an option to choose as my default browser, and configure it so I dont have to log in each time and lose my settings?
