Since we are always on the go and use our mobile phones a lot for browsing, In my opinion these are the 5 best browser that mean private
1. Brave
Brave browser is good to use & provides an excellent service. But i left using brave after knowing issue about.
2. Duckduckgo
You mean search engine right? If so, then its good. So friendly
3. Tor
Best for security but providing slow service.
4. Epic
I've heard about it but have no expriance using it
5. Firefox focus
I think this is the best browser from the list. Work so smoothly
