Why with the Yahoo redirect virus did Mozilla choose Yahoo as their default browser? After just being infected in November I thought I had become reinfected.

Found Yahoo redirect virus on my pc in November. Fixed then found in December my Mozilla Firefox was again using Yahoo as a search engine. I wasted my time looking further for viruses. Why with the a Yahoo Redirect virus out there, was there no warning from Mozilla that the default browser had changed from Google to Yahoo? After many years with Mozilla Firefox I am done!

Firefox is your web browser as Google and Yahoo in this case are Search Engines in your Search Bar.

Starting beginning of December for Firefox 34.0 and on, the Google search engine is no longer the default in en-US Firefox as Yahoo is now the default. https://www.mozilla.org/firefox/34.0.5/releasenotes/

You can still choose Google as your Search engine. https://support.mozilla.org/en-US/kb/search-bar-add-change-manage-search-engines-firefox
