Ask.com just deleted all search engines from my Firefox. Needless to say, I have never used it - probably some Add-on changed these defaults. I am using Ubuntu 8.04.
I would like all my original search engines back, but pressing "Restore defaults" just brings up Ask.com again; I'm looking for the file where these settings are stored.
How can I restore the default search engines that are supplied with Firefox? What file are they stored in?
By the way, this is a very ugly practice - removing all search engines but yourself? I will never touch their website with a stick
