Open external links in private-window

On Windows, Firefox adds a pre-set command line to the Windows registry under 

   HKEY_CLASSES_ROOT\FirefoxHTML\shell\open\command
   HKEY_CLASSES_ROOT\FirefoxURL\shell\open\command

If you change the -url in the command line to -private-window -- from

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -osint -url "%1"

to

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -osint -private-window "%1"

-- then all external links launch in a private window.

This no longer works in FF 69. As soon as I modify "HKEY_CLASSES_ROOT\FirefoxURL-F66A7FFE1BF331E2\shell\open\command", FF is detecting it and changes its status to "NOT your default browser".

I'd appreciate your help.

Chosen solution

@radar81,

Yes, I've found a solution.

Use:

[HKEY_CLASSES_ROOT\FirefoxHTML-F66A7FFE1BF441E2\shell\open\command] @="\"C:\\Program Files\\Mozilla Firefox New\\firefox.exe\" -private-window \"%1\""

[HKEY_CLASSES_ROOT\FirefoxURL-F66A7FFE1BF441E2\shell\open\command] @="\"C:\\Program Files\\Mozilla Firefox New\\firefox.exe\" -private-window \"%1\""

Replace the path and "-F66A7FFE1BF441E2" with your strings.

The status in FF preferences will change to "NOT your default browser" but *it will actually remain the default browser*.

Regards.

I am also wanting to do set external links to launch in a private window by default. I also tried the same solution proposed by jscher2000 in https://support.mozilla.org/en-US/questions/1119073 and found that it no longer works. Were you able to find a solution? Thanks!
