I have used many browser example - Mozilla, safari, chrome, explorer and many more, But opera browser is best browser. I am using opera browser since last 4 year.
I used to use Netscape navigator then, which was pretty fast and stable.
It is support all the necessary protocol, has very good stranded support and because it comes from the Microsoft stable is very well integrated with the window operating system.
opera is getting a lot of benefits and many features.
I like opera browser.
