Thanks for reporting this. I can't replicate it on Linux so it must be Mac-specific. Do you have any particular security controls turned on? For instance, are you blocking localStorage?

Is anyone else seeing this error?

It was one of the Extensions that caused the error.

Sorry, I just switched the browser and disabled all extensions (like NoScript) of which I thought that they could be the reason for this issue.

Yes, I should imagine NoScript won't play particularly nicely with CyberChef...
Thanks for getting to the bottom of it.

Ha 😄, no, a misunderstanding. I had already NoScript disabled when I visited CyberChef. It was a simple "Dark Mode" Add-on that caused the problem and I didn't expect that.
