Using firefox 59.0.2 (32 bit). Can start private browsing from scratch, but if a non-private instance is open, can't open private browsing window

I can start private browsing, from a saved icon that specifies private browsing, if no other firefox windows are open. However, if there's a non private browsing window open, this icon will only open another non-private browser. Similarly, if I am using a non- private browsing window, and click on either the mask icon, or the menu item "new private window" a new non-private window will open instead.

I'm using firefox 59.0.2 (32 bit) on a 64-bit machine.

thanks, r petrie

You need to edit the batch file to include these commands;

Here is an example (on one line only); -no-remote -new-instance -new-window

HI Fred and thanks for the response. I added: "-no-remote -new-instance -new-window" to the command line, and firefox did indeed open a new, private window. However, it only did so after displaying this error: "firefox is already running. This old firefox process must be closed to open a new window." I clicked ok, and it did just that, closed the old instance and opened a new, private window.

I had hoped to be able to keep the old process while opening the new one. Is this possible? Thanks r
