Playing video on Youtube, Youtube TV blurry on firefox 99, clear on Chrome.

more options

In the last few days Firefox has become blurry on YouTube videos and also when displaying "regular" TV channels on YouTube TV.

I have attached one screen capture of a YouTube video with Firefox in troubleshoot mode and one screen shot from Chrome at practically the same second of the video. Both represent the quality of the entire video in each browser. In the case of Firefox, the same blurry image occurs on YouTube TV.

Also in the case of Firefox, the image is the same (i.e., blurry) regardless of troubleshoot or regular mode. In the attachment, troubleshoot mode was enabled.

Thanks

I had to crop them due to file size restrictions

I don't think I've used YouTube TV, just the main site, so apologies if this doesn't work in a similar way:

If you click the gear/wheel icon on the video's controls bar and look at your resolution options, can you increase the resolution or is it capped to some low value?

If the video's right-click context menu has something similar to Stats for Nerds, that may provide resolution and Codec information for comparison between browsers.

I found that the Windows Media Features Pack can cause this if missing. However, I think this is not the cause in my case (Windows 10 Pro 64bit), as the registry key exists (see attached).

Thank you SO much. I was *sure* that could not possibly be the problem! But when I looked, ‘AUTO’ was defaulting to 360. I selected 1080 and -voila. Fixed. I may need to figure auto what caused AUTO to start defaulting that low, but it is fixed. You are a genius. Thank you

Glad to hear we don't have to dig into codec support, etc. That could have been due to transient low bandwidth. I don't know why YouTube doesn't periodically check whether the situation has improved.
