The last question with this topic was archived, and the answer didn't work.

The answer was: start firefox with "firefox.exe -private -safe-mode"

It starts neither in private mode nor in safe mode, it just opens a new window. Note that I have several other windows open, which is the reason I ask this in the first place, otherwise I could just go to about:support and restart with addons disabled and open a private window the normal way.

I use 52.8.1 ESR

If you are accessing Firefox using a shortcut, the -private and -safe-mode command options work. You need to add both of these to the end of the Target field outside of the quotes.

For example, your target line may look like this:

"C:\Program Files\Firefox\firefox.exe" -private -safe-mode

Accessing Firefox through the Windows command line works the same as well, you will just be inputting the target as a command.

Hope this helps.

Using a shortcut instead of cmd still doesn't work.
