Until recently the Firefox docs described how to use the CDP-based Remote Agent at [this url](https://firefox-source-docs.mozilla.org/remote/cdp/Usage.html), now defunct. Here is the latest archive version I can find from the end of last year: https://web.archive.org/web/20241126214503/https://firefox-source-docs.mozilla.org/remote/cdp/Usage.html
One usage example looked like this:
% firefox --remote-debugging-port
DevTools listening on ws://localhost:9222/devtools/browser/7b4e84a4-597f-4839-ac6d-c9e86d16fb83
I have tried the same but get no websocket address returned:-
```
% firefox-esr
Mozilla Firefox 128.11.0esr
```
```
% firefox-esr -h
...
...
--remote-debugging-port [<port>] Start the Firefox Remote Agent,
which is a low-level remote debugging interface used for WebDriver
BiDi and CDP. Defaults to port 9222.
...
...
```
`% firefox-esr --remote-debugging-port`
command exits with nothing returned
I have `remote.active-protocols` set to 3 in my Firefox prefs.
Please advise how I get the Remote Agent to return a websocket address for use with BiDi with FF 128. My OS is Debian-based Linux.
TIA
