I'm not a super anti-Google person. I use Gmail and Google as my search engine. But Firefox is a good browser that I use as my daily driver, and Edge, Brave, Safari and the DDG browser are other options.
Switch today and start taking away Google's leverage.
So if you really want to disrupt Google's control over the web platform the only options are really Firefox and Safari.
Google's issue if the leverage they have by having Chome used. If it is just a derivative then that lessens their leverage because the vendors of those derivative browsers do have the option of modifying Google's choices.
But if you disagree, then yes, sure: use Firefox.
