• Step 1: Open a new Firefox browser window.

I tried that and Yahoo took over again. But your reply gave me someplace to start! In Firefox I had clicked on not allowing other search engines to take over, so I did another Internet search and found this string: http://www.google.com/search?ie=UTF-8&oe=utf-8&q= which restores Google as the default search engine. I UNclicked not allowing other search engines to take over, then back into Firefox, managed my search engines to delete Yahoo (AGAIN!) then went to the config, right clicked on keyword.url, hit MODIFY and popped that string in there. It works! Now I'll go back and click again on not allowing other search engines to take over. THANKS!

Here is the reason of the problem. http://howtodosteps.blogspot.com/2011/06/what-is-spigot-inc-searchsettingexe.html You have to stop this progrem from starting. "c:\program files\common files\spigot\Search setting\searchsetting.exe"

Nothing here works (1/22/2012). The only thing I could do was go to the Firefox tab in the left corner, go to Help, click Restart with Add-ons Disabled, wait for the little window to come up and check reset everything then click restart to make Yahoo go away. Of course my other tabs went away, but I had the URLs written down anyway. Now Google is my default engine again.

I basically ended up doing the same, but I actually uninstalled and reinstalled Firefox with all default settings. I didn't know that you could "reset everything," because that would have been even easier.

Thanks all!

The right click does not work when I highlight the link

Yahoo installed as a tab in Firefox and I could not close it. I checked for Yahoo in the add on after a while I could not find the answer but I do have the answer now. Go into the add-ons. Highlight extenisons there is a program that says "Default search engine" something like that I removed that Default thing and the Yahoo tab was gone.
