For the last 6 or so months I was having an issue with youtube loading the page but not loading the video or loading it at the lowest resolution and running for under 30 second before stop and never loading again. Now I am receiving a pr_end_of_file_error on most pages for Firefox. Bilibili.com seems to work just fine. I have no proxy, no VPN, I have refreshed Firefox, and created a new profile. None of this has resolved the problem and now I am wishing for when youtube just wouldn't load the videos.
