The failure here is:

JavaScript error: chrome://remote/content/server/WebSocketHandshake.sys.mjs, line 168: Error: The handshake request has incorrect Origin header http://127.0.0.1:64282/

You will have to make sure that the client sets the correct value for the origin header or doesn't provide it at all.

1685720357260 mozrunner::runner INFO Running command: "/Applications/Firefox.app/Contents/MacOS/firefox-bin" "--marionette" "-headless" "-allow-origins" "-no-sand ... s" "localhost" "-foreground" "-no-remote" "-profile" "/var/folders/8d/wg845lkj6q54nvg5hfglhbjh0000gq/T/rust_mozprofile4GVRD6"

I just noticed that --allow-origins has been specified here which is not a supported argument at all for Firefox. Similar to other argument which might have been used but are cut-off. The options for our CDP / BiDi implementation in Firefox are --remote-allow-hosts and --remote-allow-origins.

I think that we can close this issue as invalid due to the configuration mistake. If that's not the case please let me know and we can reopen.

@whimboo is that not the latest document link? https://firefox-source-docs.mozilla.org/testing/geckodriver/Flags.html

[whimboo]

Yes, but those are the flags for geckodriver and not for Firefox.

[maheshdaniin]

@whimboo so in our tests, we use geckodriver to interact with firefox.. and geco driver is passing those flag while starting up firefox

[whimboo]

Not sure which geckodriver version you are using but it never forwarded those arguments directly but rewrites them to the ones I mentioned yesterday.
