Site not loading when using ESR due to CSP

One of our vendors websites does not load under Firefox ESR, with errors in the console pointing to CSP. Error is: Content Security Policy: The page's settings blocked the loading of a resource at inline ("default-src")

However if I load the site under the normal Firefox release, it displays correctly. When looking at errors in console, it is showing 3 errors for CSP, however it does not stop the site from working correctly. Content-Security-Policy: The page's settings blocked the loading of a resources at https://..... ("connect-src") or ("img-src")

The site is https://app.approvalmax.com If you get the login screen then the site is working otherwise just getting a green background when it is not working.

I am unsure why ESR and RR versions are behaving differently in this case. Using the latest versions of each.

This was fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=1640128 in Firefox 109.

which unfortunately was not backported to the Firefox 102 ESR.

It works in the Firefox 115 ESR which will become the only supported ESR in a month.

I'm checking to see if there is a workaround.

Which ESR?

Firefox ESR 102.14.0 I have also tested with older releases of ESR (which are deployed within the organisation) and they are doing the same result.

Thanks Mike. I have now tested using Firefox 115 ESR in my test VM and confirm that it does work. I'll need to get our team to look at pushing/deploying this through our organisation.
