Check both for their WM_CLASS in case of the default firefox it should be WM_CLASS(STRING) = "Navigator", "Firefox".
If you are lucky then the nightly defines a different one which you need to add to your custom desktop-file, like StartupWMClass=
You can use "xprop" to determine the wmclass.

This seems to be a problem of with firefox. I have played with it a bit.
Starting the firefox-nightly with a custom launcher which properly passes a custom wmclass work fine. If the nightly is restarted it looses that wmclass and obviously can't be properly matched anymore.
Having one firefox-release instance running will result in activating it if trying to start the firefox-nightly. So -new-instance is mostly required to work around that.

My last ~/.local/

This configuration is usable, but dont work right-click on Nightly and choice "Open a New Window" and "Open a New Private Window", but I had use option -no-remote.
Can you help with this problem?
Provide an answer of your own, or ask Simon for more information if necessary.
