Secure Firefox With Seven Key Add-Ons

Hi Friends,
I read one Nice Article form www.enterprisenetworkingplanet.com about Securing Mozilla Firefox.

The two most popular choices are Microsoft’s Internet Explorer and Mozilla Firefox, and there’s some debate about which one is more secure. It’s certainly true that Explorer is used by far more people than Firefox (due to it’s being part of the Windows operating system) so one could argue that, all things being equal, choosing the minority browser is the sensible choice because it offers a smaller (and thus less tempting) pool of potential victims to malware writers.
