Firefox ML features not working correctly with llamafiles. It used to. Am I doing this right?

I'm not entirely sure where the problem lies, but I haven't been able to get llamafiles to work with Firefox. It worked before.

A handful of separate commands I've tried running it with - all have the same outcome:

llamafile

@REM all commands were tried with various ports and IPs and changing corresponding ff about:config settings

llamafile.exe -m "modelname.llamafile.exe" --gpu nvidia --server --host 127.0.0.1 --port 8080 --nobrowser --temp 0 -ngl 999

llamafile.exe -m "modelname.llamafile" --recompile --gpu auto

llamafile.exe -m "modelname.llamafile" --server
llamafile.exe -m "modelname.llamafile.exe" --server
modelname.llamafile.exe --server

More info

• going directly to http://localhost:8080/ or http://127.0.0.1:8080/ in a browser tab and typing works, but not when using the firefox built-in ML stuff like 'Summarize'.

• Setting browser.ml.chat.sidebar to "False" and using firefox ml feature from context menu will open a tab with a url like http://localhost:8080/?q=I’m+on+page+“Test+Webpage”+with+“foobar”+selected.%0A%0APlease+summarize+the+selection+using+precise+and+concise+language.+Use+headers+and+bulleted+lists+in+the+summary%2C+to+make+it+scannable.+Maintain+the+meaning+and+factual+accuracy. and I can see firefox talk to llamafile server via the commandprompt window, but there won't be a response back from the llamafile server. Even typing in the chatbox and submitting it doesn't yield a response.

• In Dev Tools, I see a 404 in the POST:

No answer. Will open issue.
