Firefox won't stay the default browser

more options

None of this works.

1. There is no key: "HKEY_CLASSES_ROOT\HTTP\shell\open\command" in the registry.

2. Went through the registry and changed the values of the following keys: .htm, .html, .ttt, .htw, .htx and hxx and every entry to their reference to: "C:\Program Files\Mozilla Firefox\firefox.exe" then rebooted.

3. After each registry edit and reboot windows10 took a long time to come up with lots of disk activity. This tell me the windows changes all this back!

4. So, how do you fix this??????

What is Windows changing the default browser to? Normally, the only reliable way to change it is to use the "Default apps" control panel.
