Ich bin leider jetzt furchtbar neugierig, wo die Vorlage herkommt, wonach kann ich bei knowyourmeme o.ä. suchen?

You can, another comment mentioned that. Only, I didn’t mean to spread misinformation because I haven’t used anything else in years.

I was amazed to find out you can open a new tab by using middle-click in firefox.

Fair point. My browser (FF) supports ‘search in tabs’ as well and suggest it over a new search engine result when typed in the address bar. I don’t know what about the style makes me think this, but it looks like FF on Windows in the Screenshot.
