There are so many different web browsers available, it's a hard task for those who aren't as "geeky" as others to make the choice. Most operating systems currently come with a browser, such as Internet Explorer with Windows, or Safari with a Mac. Are they the best option?
With Firefox, Chrome, Safari, Opera and Internet Explorer on the market which one should you choose?
Are you looking for super-fast page loading? Chrome might be worth a try.
Is it compatibility you are looking for - Try Firefox.
It is a matter of personal opinion, and how many "bells and whistles" you want.
Trends in popularity show that all browsers are dropping in popularity except for Google Chrome at the moment, due to the fact that is is compatible with the vast majority of sites and it's quick and very simple to use.

There's nothing stopping you installing more than one browser, it's possible to run them in parallel and find what suits you best.
