Hi Wildamberhoney,
I am happy to see you interested in the famous 'Browser War' question; I will try to provide you with an answer based on years I spent programming HTML and Flash.
Let the tournament begin:
1. IE: INEFFICIENT AND DANGEROUS
PROS:
- Widespread: so you will find it in almost every environment (friends, work, travel, internet cafe...)
- Compatible: It comes with all you need to play embedded videos, plug ins are easy to find and all websites and servers will identify it outright.
CONS:
- Plagiarism: Don't get caught up in all the hype of "IE 7" and its revamped tab browsing; it's clearly all bark and no bite, and a clear copy of Firefox's features.
- Lacking Security: it is "integrated" in your OS, and with proprietory technologies like Active X, it is constantly exposing your pc to external threats (trojans, phishing, hacking...).
- Bad Performances: it is slower than Firefox, Opera and Safari. It is also worth mentioning that it suffers frequent freezing and is forced to close most of the times.
2. OPERA: LIGHTNING FAST AND INNOVATIVE
PROS:
- Speed: and even more speed. That is a real edge when you browse a lot. You can browse a dozen tabs without a sign of slowdown.
- Trend setter: The latest release can handle BitTorrents quite well, has a cool separate downloads page and is really good looking. This is the looker of all browsers.
CONS:
- Alien interface: you mentioned it, it has sometimes a "weird" feel, and some advanced functions are still to be understood by the average user.
3. FIREFOX: THE OVERALL WINNER
PROS:
- Balanced: it is free, fast, nice looking, handy, small on the hard drive, and has the indie cool factor.
- Growing: more and more people on both Windows and Mac OS X are using it, giving it both credibility and motivating Mozilla to keep it updated and improved.
- Customizable: with the Firefox add ons and applications you can make your Firefox just right for you: I advise you McAfee Security Advisor and Fasterfox as a starting package, they can greatly improve your ride on the network.
CONS:
- Compatibility: You will have to spend some time downloading the right plug ins for videos (the plug in for windows media can be a real nightmare!), and some stone age websites are still not running on it.
(BONUS) SAFARI: MAC WINNER:
I know I am a Mac freak and Safari was not in your question; but if one day you are working on a Mac OS machine, I suggest you to take some time browsing with Safari. It is still my favorite browser (simple, fast, friendly...), but I have to declare Firefox winner since it runs on both Mac and Windows.
So here it is, but what really counts is how good YOU feel with one or another browser; so try them all, make up your mind, and I hope you will find the one that gives you the most enriching ride on the Internet!
Cheers.
