Errors when attempting to save rules?

[bryangingechen]

Hi, I just installed the extension in Firefox 121.0 (on macOS 14.2.1) and it didn't seem to be working, so I tried to investigate by "inspecting" the add-on in Firefox to open the dev tools.

With the example rule given in the README (host: "*.example.com", language: "en"), I clicked Save in the preferences and got the following output in the "Accept-Language per site" console:

Basically, "Error: urlFilter should not start with '||*'" is thrown when the rules are assigned.

I tried changing the host to just example.com and then tried saving, but then I got "Error: An unexpected error occurred" instead at the same point.

I even tried disabling all my other extensions, but I still got the same errors.

Let me know if there's anything else I can do to help.

edit: I just tested this on my Windows 10 machine (with Firefox 121.0) and got the same errors.
