Why is there a red bar with a little camera icon when I minimize safari?
It seems to happen when I use yourdailygerman.com ?? I took a screen shot after I minimised it.
Question marked as
The website asked me if I want to allow the use of the microphone when I visited it.
They provide an audio (and maybe video) communication service on their website (given the website's contents, probably for language testing, I suppose).
Safari notifies the user when a website make a request involving the microphone and/or the webcam.
