I, for one, am always on a looking for new browsers to try out. Currently using Firefox (for FB, Linkedin and Gmail), Chrome for Youtube and Safari for everything else [2].
In addition to usual suspects such as Firefox, Safari, Chrome and Opera I’m listing here a few alternative browsers from previous HN discussions:
Blisk, a browser for web developers - https://blisk.io/
Ōryōki Web Browser - http://oryoki.io/
A smarter web browser - https://minbrowser.github.io/min/
Brave - a browser from the co-founder of Mozilla Brendan Eich - https://brave.com
Vivaldi by the co-founder Opera - https://vivaldi.com
