I'm not sure that will affect this. I believe that's for updates to user-installed search engines, which are distributed and updated separately from the browser. Default search engines are part of the browser code itself, so they update when the application does.
Note that Google will still be included as an option, so all you need to do is click on the search box icon to choose it.
(I'm an occasional Firefox contributor and I once worked on the search engine and add-on manager code a little bit, but I'm not an expert so take this with a grain of salt.)
