So this is a CMS website I use for work. I can go onto the website and parts of it display but parts of it are missing. Inspecting the website it appears that a number of files have the error 304 Not Modified, most importantly a JS file. Is this because the browser cannot read the code? or would it be something else that could cause this? I know that the website was written in React, is this supported by tenfourfox?

    What's the website? What happens if you empty the browser cache and the visit the site (History > Clear Recent History > Cache)?

    So it's a management site that we use for work. If I give you the link it'll only show you a login page and nothing else. Thanks, I gave that a go but still nothing. It could just be that the javascript library is not supported by tenfourfox. It also mentions a 'Cross-Origin request block', maybe this is blocking some kind of request.

    That's probably it (Cross-Origin request block), but without proper testing I can't say for sure what it is and/or how to solve the problem (if possible).

    No problem, that makes sense. On a refresh that error has now gone away. But I've looked into it and it seems like it was made with 'create-react-app' and I remember a dev post saying that Async wasn't entirely supported in tenfourfox so it could be that (https://create-react-app.dev/docs/supported-browsers-features/). Thanks for the help anyways.
