Did Firefox drop support for the Windows DDE interface?
The DDE interfaces to query the webpage open in the current tab or to open a new webpage has been available for a long time but the last update seems to have removed it. The other options is that it changed the application Id but this seems unlikely.

The service is still available, it just does not return any reply when requested:
Using Tcl/Tk (System32) 2 % package require dde 1.3.3 (System32) 3 % dde request firefox WWW_GetWindowInfo -1 remote server cannot handle this command

Everything I find is really old except for the above.
Please let us know if this solved your issue or if need further assistance.
Thanks, command line options would allow opening a given webpage but I was using mostly the 'get the current open webpage'/WWW_GetWindowInfo for my own password manager that I wrote and never released. Push a button to get the user/password for the current website and then copy/paste it. This DDE interface was working on IE, Opera and Firefox, Opera is gone and Firefox seems to have broken it in 57, only IE (not edge) still supports it.
