I meant to say on why the google search bar is on the speed dial page that: My understanding was, from comments in this forum, that that was a financial arrangement -- Google paid Opera to help Opera develop the product and not charge the user of the browser a cent. And Opera does let the user hide the Google search bar if he or she don't want the Google Search bar in their face or taking up browser space. Here's something similar I found on Firefox -- where Google paid Firefox to have it as the default search engine.
In that 2011 article it is is noted that Google pays Mozilla almost a billion dollars to be the Default engine in Firefox, and it is through deals like these that browser developers are able to offer their product for free.
