Specifically Youtube videos and nothing else either don't load at all, load only the first 10 seconds and then buffer, or load partially after ~20 minutes. No error message. Only in Firefox. I tried: Reinstalling Firefox Switching profiles Disabling all extensions Running in safe mode Clearing cache and cookies It's been like this for a couple of months. Been circumventing it by playing videos in a different browser, but would be nice if I could fix it.
