Youtube Videos Never Loading?

more options

Hi all-

I've recently switched to firefox and my only complaint is that Youtube does not appear to be functioning it well. Frequently videos will just never load, remaining a black screen with the circle spinning. The rest of the page loads, but not the video itself. I've left one of these pages open for four hours and it did not load at all during that time.

Once I had a video that was playing just fine, and I accidentally hit another video on the side of the screen. When I went back to the one that had been playing, it was now a black screen and the endless loading circle.

There doesn't seem to be any rhyme or reason to which videos will actually play and which will not, other than I've noticed it happen a bit more frequently on videos uploaded in the past twenty four hours.

I've uninstalled the browser and reinstalled it, cleared my cookies and cache, made sure firefox is up to date, everything I can think of doing. I've not been able to find anyone else mentioning having an issue with this. No other browser on my laptop seems to do this with youtube, just firefox.

Any suggestions? It's getting pretty frustrating.

Try to disable IPv6 (check for other possible causes as well).

Thanks for the suggestions!

I tried disabling IPv6, disabling DNS prefetching, cleared my cache again since I saw that on the list and removed all extensions I have installed.

I've run a malware scan recently, after this started, and found nothing.

Unfortunately, none of those things have worked.

Maybe check the Timings in the Network Monitor.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

I don't see any content being blocked using those tools, and unfortunately reloading the page like that doesn't solve the issue either.
