In November, Firefox announced it would switch its default search engine to Google. Firefox, representing 16% of all internet browser usage in the U.S., is a considerable loss for Google, assuming Firefox users don’t switch back to Google manually. In order to bring users back, Google has taken some considerable measures to get people so make them their default, including this message that appears at the top of search engine result pages when searching Google on Firefox:
It’s a fairly large message, taking room away from organic results. Yahoo’s search results have moved from 8.6 percent to 10.9 percent since the change to Firefox default in November, enough for Google to take notice. Clicking “No thanks” once will remove the message, but it may come back.
