I found an obscure article on the internet about disabling the Google Doodle on Chrome.
You paste this line into your chrome browser bar:
chrome://flags/#use-google-local-ntp
and the highlighted line will have a drop down menu under it that you change to Enable. Then restart Chrome.
I use a chromebox that uses chromecast on my TV, so I doubt it would work on Firefox, and I don't really understand most of what the article is talking about, but it worked for now.
