For years I have set my own idea of a favorite search engine in Firefox. I tend to like DuckDuckGo.
I find now, when I drop something into the address/search box, The search engine used is Yahoo. If I go into the options and change my default search engine to what I want, it works with that search until I bring Firefox up again — then it reverts back to “Search for Firefox”, which I guess is an alias for Yahoo.
I suppose I didn’t read some EULA completely and that is how Yahoo got inside the system. Any ideas on how to purge it? I have no real fault to find with Yahoo, except this should be my choice to make — not someone elses.
