Firefox all the way
I don't use Chrome because Chrome keeps your browsing data. Everything you do on the web is collected by Google and they sell it to the advertisers. Huge privacy issue with Chrome and I'm not a fan of this.
Firefox, on the other hand, is open source, care about users privacy. Firefox currently is as fast as Chrome. So, happy with it
And don't use crappy Chinese browsers like UC Browser. They are a privacy nightmare. If you prefer the Chromium ecosystem then use Chrome/Opera.
