Have been getting this for months and only just located this GitHub issue for it.

On Linux with regular Firefox. Get a different issue on running dev on Firefox (it starts but the extension doesn't appear) and running it on a different gecko browser, Librewolf (it errors during the start script if Firefox not installed - if Firefox is installed it starts Firefox instead of Librewolf).

Happy to help spend as much time as you need debugging it as I've got a perf issue that is only affecting Firefox and it's hard to debug it effectively without extension dev !
