That sounds more like the home page and search settings. These are usually not affected by reinstall (long reasons why) and Firefox now defaults to Yahoo search. Noted at https://www.google.com/#q=firefox%20default%20search%20engine%20changed%20to%20yahoo
I don't want to upset you but do you know how to change home/opening page and search settings?

Client I s having default browser issues. When clicking firefox browser to open shows up with this link:
http://search.yahoo.com/?ei=utf-8&fr=tightropetb&type=11083_020415
I have tried to virus scan with combofix, malware bytes, and spybot. I have tried to uninstall and reinstall firefox and I have also went and tried in FF options to change it back to Google homepage. After I change options or reinstall page comes back to link above. Any suggestions would be helpful on resolving this issue. Client only uses FF 2nd dairy browser not affected until uninstall of primary browser with link above shown.
