In trying to open Firefox, I keep getting a Google apt, why?

How about showing the issue... What OS? If windows, home or pro? If windows, are you running any security software besides MS Defender? What version of Firefox?

Hi

Google is the default search engine in Firefox. This support article will help you to change this:

I hope that this helps.
