Firefox sometimes blocks or loads streaming-related websites differently

Hi, I’ve noticed that Firefox can sometimes behave differently when opening websites that contain a lot of embedded media, scripts, or download-related information. I was testing this with a site called BeeTVHub (https://beetvhub.com/) and wanted to know whether there are any Firefox settings, privacy protections, or extensions that commonly cause parts of a website to load incorrectly. For example, are there particular settings I should check if a page loads normally in another browser but some content doesn't appear correctly in Firefox? I’m mainly interested in understanding whether this is expected Firefox behavior or something specific to the website. Thanks.
