https-only exception not working?

using Firefox Developer Edition Version 130.0b5 (64-bit) https-only mode is enabled for all windows enabled, with a couple exceptions. one of those exceptions is www.bom.gov.au , which does not support that mode. anytime someone tries to open a page from there in said mode, leads to a page that redirects to it's homepage, highlighting that it is unsupported, and changing from any specific url to the redirect url. in the past it worked well to have this page listed under the exceptions for https-only, always loaded without a hitch. but now it's treating the page as not an exception. i've removed it from the exception list and tried loading, re-added and tried loading, but the result is always the same. can anyone please help?
