I would go back to Firefox if the Waterfox project folded. I have not been a fan of data collection but I wouldn't mind using Firefox, partly because if I really want to remove the parts I don't like I could find some way to remove them or block if I want to.
brent In advanced settings I elected not to share any data with them.
I am fine with that. If you find what Firefox has for security as fulfilling for your needs that is great, I don't get picky, I might suggest anyone reading this at least look into Firefox, Waterfox, TOR if you want to go this route, or what you would consider secure. If interested in a Chrome alternative I have used Vivaldi, it has been stable for me, Chromium, stable just like Vivaldi in my experience.
