Can't open new tabs in Firefox from the command line on a Mac

If I run

   /Applications/ -new-tab

when Firefox is already running, I get the error "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." It is true that Firefox is already running, but what I am shooting for is getting a new tab in the already running instance, as the -new-tab flag indicates. I get this problem even if the already running instance was started with exactly the same command.

Some of the flags at explicitly say they open new tabs or windows within an existing instance of Firefox, such as -private-window, but I get the same behavior with those flags. What am I doing wrong?
