My default search engine (in about:preferences) is Google. Yet suddenly Yahoo search has hijacked my default searches! (And I don't even have Yahoo search as a listed search engine.) Also in about:preferences, I have "Use the address bar for search and navigation" unchecked--but the URLbar treats my entries as searches! What can I do to fix this?

Have you recently installed or updated any extensions?
Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

Yahoo search hijack is gone! (Permanently, I hope.) All I did was to put Fx into safe mode and then restart in normal mode. I did not change a thing. Very strange indeed.
