Command line

./llama-server -m /Users/$USER/ml/qwen/qwen2.5-coder-32b-instruct-q5_k_m.gguf -c 8192

Problem description & steps to reproduce

Using latest master on MacOS to run llama-server on localhost, the web interface doesn't seem to work in Firefox, but works in Safari and Chrome.

Firefox brings up a modal popup with:

127.0.0.1:8080

TypeError: conv.messages[0] is undefined.

and then after clearing that popup, another appears with:

TypeError: ResizeObserver.observe: Argument 1 is not an object.

After which there's just a blank page. I can't see anything else in the DevTools Console.

This is with Firefox 134 on MacOS, (M1 silicon), and as mentioned above, the web interface works fine with Safari and Chrome on the same machine.
