Mozilla Firefox is the one of the most used browser among internet surfers.
I am using this browser since I know how to browse web. I had nearly used all the browsers like Opera, Safari, Chrome but Mozilla firefox is best among all of them. It loads the webpage in low speed of internet. There is high security for bad websites which are harmful to computer.
Mozilla firefox has a features to automatically block suspicious sites.
You can also add various add ons in the browser and different plugins according to their purpose. I used to visit Youtube most of the time on internet and mozilla firefox operates youtube very smoothly.
I recommend you to install the latest version of this browser.
