By default, firefox set this as my homepage: http://www.google.ca/firefox?client=firefox-a&rls=org.mozilla:en-US:official (it doesn't show Search Suggestions when I start typing) But at http://www.google.ca/ they do show up. Well, I'm offering this more as a suggestion than a question because I know I can simply change my default homepage to http://www.google.ca/, and Search Suggestions should show up. But many firefox users may miss out on google's functionality without even realizing it, so I think this should be looked into. Otherwise I use firefox all the time. Great browser!
