What's the difference between IE, Opera and Firefox? Which one is the best of them all?

Which of the three browsers are good? And why? Is any of them better in terms of faster web browsing, or better security, etc. etc.? Which one do you recommend? Are there any other web browsers out there that you use, besides the three that you really like?

Considering a change of web browsers (currently using IE) but I don't know which is best. I heard that you need to tweak your Firefox a lot (for enhanced security), so I'm not so sure if I'm up to that. Any ideas what I can use?

Opera is best, Firefox is second. You don't need to touch either one for security.

never used Opera

but Firefox is way better than IE
Firefox is the best in my opinion. It has faster browsing, a lot more security, and it blocks pop-ups. IE has a ton of security flaws with it, even with the patches. Not many people use firefox, the majority uses IE, therefor hackers all target IE.
I dont know, but i like firefox.
Microsoft pays its engineers quite a lot of money to make good software.

It's just that a lot of other (unpaid) people who have too much free time (since they don't work, adding to the unpaid factor) like to write viruses and spyware for IE.

Since Opera and Firefox are less frequently used, most people don't bother writing things to hack them.

But IE is integrated into your operating system, and can be activated from the run menu, and it's perfectly safe if you visit normal websites (non-warez type deals), I suggest IE.
Opera the best then it's firefox. I use firefox the most because you can view internet explorer websites that Opera can't gettin the IE tab extension. Opera is faster than Firefox though. IE is stupid too many flaws. It's so many it will take too long to describe them. To make a long story short Firefox is the one you should use.
FF is the best between IE and FF (never used Opera but I've heard it is good). FF has much more built-in security than IE, not to mention tabbed browsing, themes, and extensions that can allow you to customize your broswer, something IE can't do. FF 2.0 is supposed to give you the ability to recover your bookmarks after a system crash (something you could already do if you know how).
Firefox and Thunderbird are great Open Source working PC programs.

Firefox/Mozilla are good because,,,,,,,,,,no MS branding. You are allowed to change it to anything you like, make it work the way you want it to. Its your pc, kinda, so enjoy the freedom.

Security? there is no security on the Internet. We just bounce along, allowing governments,corps,cops and just about anyone to observe. Want security, get a blanket, unplug the pooter from inet and play solitaire.

Its a strange world, live in it, enjoy the moments that we have and peace be on all.
