and that's just another reason to hate Yahoo
I have been changing the default search engine back to #Google on all installs of #Firefox that I do (and since I push it out via Active Directory at work its more than a few) since #Mozilla made the deal with #Yahoo years ago. It wasn't so much that the quality of the search was poor as it was that more than once the top result of a search on Yahoo was a paid ad serving malware! I just couldn't trust Yahoo. Yeah Firefox had gotten slower compared to Chrome but I don't need to get infected with malware faster anyway.
Yahoo parent sues Mozilla for replacing it with Google as Firefox default search
