What happens if you click?
Try right-click, "View code", and see the names of this block is the name of some program or extension that does it. Also, you can dig right of the tab styles, or Event Listeners, there can be styles of extension, determine who it's from.
Well, or put the ad blocker and simply block this piece :-)

Yesterday there was a switch and under the search item was a few lines written in English. I do not remember what was written verbatim, but the essence was that it related to the background of your browser. Type are every day new backgrounds to be loaded and change. Today, this garbage is gone)
