Mozilla has pulled a "Chrome" by adding a search box to the new tab page in Firefox 31, which reached beta status yesterday and is slated to ship in final form on July 22.
Along with the nine thumbnails representing the user's most-frequently-visited websites, the new tab page in Firefox 31's beta sports a search field near the top of the window. Typing a search string in the box initiates a search on Google, unless the user has changed the default search engine. If the Firefox user has changed the search engine -- say, to Yahoo or Microsoft's Bing -- that choice is also used in the new tab page's search box.
