I've managed to bug my PVE install.

I have managed to aggravate a bug. When accessing the PVE admin web interface from firefox, the UI no longer updates to reflect the state of the system, e.g. the PCI and USB devices passed through to a VM, or tasks in the tasks log.
It functions correctly when accessed from chrome.

See the presence of usb2 on the right, and updated logs.

Not sure how I produced this. I did run the Upgrade function at close to the same time.

Additional symptom is that the web UI's shell does not work with "Invalid CSRF token."
I wonder why it'd only be broken on firefox. I found a thread that discusses it. I'll see about resetting those components tomorrow.
