Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.
My choice is Mozilla Firefox and may be because I used it for a long time. So I am a bit used to it, and it also works well enough to make it your default browser. There are many other browser I may prefer If I'll have to instead of Firefox than I would choose Opera as we all know about its speed when opening web pages specially working in windows.
mozilla firefox beta 4, is my default browser now. i believe it is the best browser and 200% faster than chrome.. before this i was using Google chrome as my default browser, but now as i often use plugins so i migrate to Mozilla FireFox again. another thing for what i am using mozilla is its personas themes. hundred of personas themes updated daily and easy to apply so that makes this browser with more fun work environment.
Chrome is the best browser and I use Chrome only. There are other browsers other then Chrome and they are Mozilla Firefox, Internet Explorer, Safari, Opera etc. Chrome is faster then other browsers and have features like, easy to operate, reopen closed tabs, good design and graphics and many more.
I was using Internet Explorer later on I used Firefox but now I'm using Google Chrome. Google Chrome is light, fast and save and didn't had any crashes yet so for me it is the best browser. Its very good for my business also.
