Google is clearly feeling the crunch from Mozilla moving to Yahoo as the default search provider. I noticed this today on Google (I use Yahoo primarily but do use Google too).

After clicking this it brings up an overlay with instructions specifically for Firefox users and notably I did not get this message in other browsers I tried so clearly this detection code they added is specific to trying to win Firefox users back.

I wish Google instead of trying to fight over search dominance would instead focus on building an awesome open web with Mozilla and others
