I try to use the web editor.

Well imo this is a very simple editor, who needs much more functionality, in the future.

My main problem at this time is, How to select a Port nr ??

Select a Board is no problem, but a Port ??

OhOh
I Read on this forum that also Chrome can be used as browser.
Until now I use Firefox.

Indeed in Crome I can select the Board and Port !!

So far so good

Halleluja..

It works just the same in FF too as it does in CHROME or EDGE or safari.

However installing the certificate used in FF is a little different from CHROME and not always as obvious.
It is my thinking that the certificate was not properly installed for FF in your case.
