Firefox being provided the incorrect language pack.

[pliant wasp]

So I have firefox set to use English GB , which is the only dictionary I have installed (image 1), despite that in the language settings it shows a US pack (image 2).
This is an issue because the spell checker forces it to use a United States language (image 3).

I've gone through a bunch of files for firefox to see if I can locate that US pack so I can forcefully remove it. However I havent found any language pack besides the one I have installed for GB.

What I think could be happening is linux mint is providing firefox with that US english pack, cause firefox really doesnt seem like it has that. Is there a way that I can locate the file?

I did try to search with grep "en-US" but that doesnt do anything 🥀

I think grep -r "en-US" might show it somewhere, but that just prints a billion things to the terminal, and some results dont even contain that string

grep: .config/Code/User/globalStorage/ms-dotnettools.vscode-dotnet-runtime/.dotnet/9.0.8~x64/shared/Microsoft.NETCore.App/9.0.8/System.IO.FileSystem.DriveInfo.dll: binary file matches
```so why that even shows up when it lacks `en-US` i dont know
