Will not play any youtube videos - only get spinning circle

[dootsie5times]

What happened?

On Sunday, 3/9/25 I was using waterfox 6.5.5 and youtube was working like normal. However, on Monday, youtube stopped working. Any video I try to play just gives spinning circle and never plays. I tried troubleshooting mode, no joy, then tried refresh, no joy, then tried fresh install of older portable version of waterfox, still no joy.

Firefox version 135.0.1 plays them fine.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
