Introducing the New Firefox: Firefox Quantum - The Mozilla Blog (https://blog.mozilla.org/blog/2017/11/14/introducing-firefox-quantum/)
Oh neat. I love firefox but my problem with it is that its just so much slower than chrome, I'll give this a try.
Edit: on it now, very good first impressions.
Looks like Firefox.
I use Opera... well it is now more like a Chrome with Opera features... love it.
Now if you want something new and modern UI... you should try Opera Neon.
