Yahoo hijacked Google Search in Firefox
A pop-up showed up while I was in Firefox. I thought it was from Firefox, looked official, etc., and wanted to update Flash. I continued with it only to find out it was Yahoo hijacking Google Search in Firefox. The pop-up showed up again (see image). I've tried to find out how to remove Yahoo from Google Search through Firefox where it occurred, but everything I read just sends me in circles. Hopefully, you've tacked this problem and have answers.
