I've tried setting my default search engines (even though Yahoo isn't even included); I've tried checking the addons and deleting them all; I've tried deleting the application as well as my user folder and ~library files (doing a clean install from Mozilla's website); I've tried installing MalwareBytes, running a scan and rebooting. Nothing so far has worked. Every time I reboot and attempt to search from the address bar, I get Yahoo Search results.
