The Bugbug bot thinks this bug should belong to the 'DevTools::Inspector' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Might be similar to Bug 2042101

By any chance do you have some addons installed? This issue triggers very frequently for me when Stylus is installed.

But it is not the culprit, I think it might be multi account containers.

[Julian Descottes [:jdescottes]]

Thanks for the answer!

It can be another addon, it's not specific to Stylus, even if it is known to trigger the issue.
I'm hopeful this should be fixed by Bug 2042101.

If you still have the issue with Firefox 154, let us know.
