Recently, I have found a "search here" bar in the upper part of my firefox window. And what's more is that there is a similar bar for google next to the Navigation bar. It seems a bit redundant to have two of these things. So I want to know how to get rid of them? I've gone through the various forum posts here and none of them have been helpful.

Though I'm wondering if this is part of the new version of Firefox or if this is something else. If it's the latter then I'd like to know how to get rid of it. Please let me know as soon as you can.
