Nice, thank you.

I had Codex take a look and all it suggested for compatibility with Firefox was adding background.scripts to manifest.json, where you currently have background.service_worker for Chrome.

 "host_permissions": ["*://forum.toribash.com/*"],
    "background": {
        "scripts": ["background.js"],
        "service_worker": "background.js"
    },

I made the change and was able to load up the extension in Firefox but it was a bit buggy, which is to be expected since you're building for Chrome. With your permission I'll keep hacking away with Codex, if you'd rather not have AI running over your hand written code I'll stop immediately.

Thanks again for this extension, I had a play with it in Chrome and it's super smooth and a huge quality of life improvement for browsing the forum.
