A browser's capability that's beginning to be important in today's age of various scams all over the internet is security. Again, we see that all the browsers have this capability, but security experts claim that Firefox leads the team with respect to integrated security and anti-phishing tools.
Last but not the least, is the speed of the browsers. But in so far, as the faster browser is concerned, we hit a certain problem. At this point, it is unsafe to speculate because there are too many speed results published all over the internet. I could not be absolutely sure which is the fastest.
For example, just recently, when google chrome was l;aunched, experts claimed that it was 4 time faster than safarti, firefox, IE and Opera. however, during the same week, safari released another update and improvement of their browsers claiming faster processing of pages making them twice as fast as the recently released Google chrome. And immediately after, Opera released its Alpha Version of Opera 10, which again claimed to be the fastest in the browser competition. And if that was not enough, just a week after, Google announce it made significant and snappier developments., the declaration go on an on and users are confuse: Which one is really the best?
Well there is one thing that i am sure of: Despite the usability and security of Firefox, IE still has the largest sale on the market worldwide, but developers of other browser are claiming that they are catching up extremely fast as more and more people are depending on firefox and in their everyday browsing and Internet experience.
