Since the automatic update to Sequoia 15.6.1 on my iMac, YouTube now freezes, and sometimes doesn't open in another tab, says, "account.blank" but MAIN QUESTION IS: Is there a bug in the 15.6.1 update that causes YouTube to freeze on Firefox?

Original Title: After update to Sequoia 15.6.1, my YouTube freezes on Firefox. Is there a known bug AND workaround?
iMac 24″, macOS 15.6
+1 I have no problem with YouTube videos running 15.7.1 using Safari or Firefox.
I also recommend updating to the latest macOS, Safari and Firefox versions.
Plus uninstall any third-party Anti-Virus, Protecting, Cleaning software and/or VPN(s).
Make sure you're up to date; Sequoia 15.7.1 & Firefox 144.0. I have no trouble with YouTube on an iMac Pro running them.
If present, try if disabling or uninstalling AdBlock extension helps. Or use Brave browser instead.
Just to add, try opening Firefox in Trouble Shooting Mode.

I would hesitate about installing the "latest" macOS as part of a solution to this issue. The "latest" is macOS 26 which is a complete remake of the OS and upgrading now might add a lot of other distracting complexities you may not wish to deal with at the same time. What you should do is make sure you have updated the latest Sequoia version 15.7.1
I have no issues with YouTube in the latest Firefox and the latest Sequoia and using uBlock.

You're right, I should have specified the latest version of Sequoia.
