You also seem to have been infected by Conduit software:

• browser.newtab.url: http://search.conduit.com/?ctid=CT3320835&octid=EB_ORIGINAL_CTID&SearchSource=69&CUI=&SSPV=&Lay=1&UM=2&UP=SP94703A03-D5F4-4326-A8F7-2F2EB2AF2F9E

You can check your installed extensions:

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

You can check in "Windows Control Panel > Programs" for recently installed programs to see if anything from Conduit or any other suspicious software shows up.

You can use the SearchReset extension to reset some preferences to the default values.

• https://addons.mozilla.org/firefox/addon/searchreset/

Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
