Is your search going to Bing when you type 1 word in the URL/location bar? Do multiple word searches still go to Google? Did this start this week, after the Microsoft updates? If so see: https://support.mozilla.com/en-US/forum/1/694752?

See this: http://vistasupport.mvps.org/run_as_administrator.htm

Nothing you stated is the situation it is just that it uses Yahoo! search and I want to use google. I am not impressed by bing or yahoo is all.

I have the same problem. Can't figure out how to make Google instead of Yahoo my default search engine.

hell ya i tried the keyword.url in about:config and change it to google's url but still the problem remains unaffected. I still cant figure out how to set google as default.

I had this problem too, it turned out to be a yahoo based toolbar bundled with PDF creator, even thought the tool bar was not active in firefox, uninstalling it solved the problem
