@violoncelloCH any error in the console? It works here for me on chromium! :) But on FF I have a "Strict-Transport-Security: The connection to the site is untrustworthy, so the specified header was ignored"

PS: not a regression, this feature did not existed on the previous version.

Ah, sorry, I thought it had worked before.

Firefox 64.0 in the console i get output
