Firefox is far safer and easier to use than Internet Explorer. It looks nicer and can be customized, and has the best tabbed browsing features of any other browser at the time of writing.
Heck, it even comes with an optional spell check feature that checks spelling in boxes you can type into - It won't affect normal sites!
www.getfirefox.com - A download smaller than IE, Opera or Netscape.
Once it is downloaded, just double-click the installer you downloaded and it does the rest for you. If you use IE, FF asks if you want to import your bookmarks - It's totally safe, won't affect IE at all.
Seriously, Firefox is so much better as a browser. Sometimes pages are made specifically for Internet Explorer- Firefox will ask you if you want to install plugins that will allow you to share in that experience.
To anyone reading this that hasn't made the switch yet- Do it!
If all else fails, you can (if you're stupid enough to ^_^) completely remove Firefox and leave Internet Explorer completely untouched.
And I'll note here that Star Wars Combine has completely put me off due to it's no free email policy, as it alienates legitimate hotmail users like myself. I thus assume that the game is in no way worth my time because it can't afford a better system. I'm not going to waste the effort acquiring a non-free email account for the temporary job of signing up to a seemingly snob-based community too good for hotmail. Your loss, since you won't have my support. I only posted here because I saw Firefox mentioned - I love and support Firefox (because it supports me, unlike some "services".....). And with that, I'm off to play Runescape.
