1) I've enabled dom.dialog_element.enabled = true (after https://caniuse.com/dialog).
2) click on button "Click me" in https://alligator.io/html/dialog-element/, dialog does not appear,
3) InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

But In Chrome dialog appears.

Don't mess around in about:config if you don't know what you're doing.

Sorry, dialog appears. My mistake. There were not an issue.
