The old URL just loads a white page and I also don't know why that should be documented on a page for "Firefox profiler".

This was a hard search to find that though, because for some reason the official docs name it "browser's toolbox" (searching for "enable remote debugging" was less fitting then), probably, because debugging a WebExtension is just a side-effect, so yeah… I can see how that comes from.

It's way easier to find that low level stuff like the protocol. 😅

And unfortunately the nice WebExtensionWorkshop page, which is also from Mozilla, also does not offer any information on that topic, just in-browser debugging.

…debug

In firefox-devtools/vscode-firefox-debug#393 I've found out, that the possibility of debugging extensions using an external program is not even mentioned at all here.

I guess at least such a minimal version like this would be useful. The way how to do it is then documented there.

Ah the extension seems to use port 8000 when not configured otherwise, my Firefox uses 6000. Maybe also add devtools.debugger.remote-port for information to change the port?

Actually though, even though devtools.debugger.remote-port says port 6000, it seems to use some random one. I had to use the mentioned "browser tools" (see doc link I added), and it said there this port is used:

Client-Endpunkt: 127.0.0.1:56950
Server-Endpunkt: 0.0.0.0:33835

Then I just configured it to use the server port. I am confused?
