I recent fell into a trap setup by uTorrent and Yahoo. I am used to the older uTorrent days where you did not need to really pay attention do what the prompts say and the last one was to change all your default search settings in browsers to Yahoo. Being the Google Boy I am I obviously did not like this.
To fix the default URL search on Firefox follow this:
1. go to about:config in the URL bar
2. Search for browser.search.defaultenginename
3. Change the Value from Yahoo back to Google.
To change the search box on the right in Firefox I just used the little down arrow and changed it back to Google.
I’ve learned my lesson read ALL THE PROMPTS!
