Ahh ok ...I searched for an answer too and I didn't find anything. The only thing I could think of is that the browser likely supports the ability to turn features on and off and I was thinking you might be able to locate a way to turn the floating overlay off. If that floating overlay search box is the only way you do a search on that browser then you would have to navigate to an individual search engine's home page of your search choice. Google? Bing? DuckDuckGo? Every time you wanted to search for something. That is pretty much how I do it on Chrome. =)
