Good question programming code or what?

I was just about to correct a small spelling mistake in my question and a programming window has just opened on my laptop. Similar to MSDos or C64 earlier. Or does that belong to Windows? I have almost no idea about such things but I find that strange.

Then close the console again. Firefox: Ctrl + Shift + J. Or another window that you can close again in the menu under "Web developer".

OK, thank you, I thought something like that, but the questions were gone too, so I asked them again. I think the whole connection was gone for a moment.
