I've used Explorer for years, but I'm slowing migrating to Firefox. It's user friendly, opening tabs for multiple sites rather than launching new sessions.

1. Download Firefox @ http://www.mozilla.com/en-US/firefox/
2. Check out available add ons @ https://addons.mozilla.org/en-US/firefox/

Here are a few to consider

Firebug @ https://addons.mozilla.org/en-US/firefox/addon/1843
You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

Greasemonkey @ https://addons.mozilla.org/en-US/firefox/addon/748
Allows you to customize the way a webpage displays using small bits of JavaScript. ...

Fireshot @ https://addons.mozilla.org/en-US/firefox/addon/5648
This plugin provides a set of editing and annotation tools, which let users quickly modify captures and insert text and graphical annotations.

Delicious @ https://addons.mozilla.org/en-US/firefox/addon/3615
Integrates your del.icio.us bookmarks and tags with Firefox and keeps them in sync for easy, convenient access.

Clipmarks @ https://addons.mozilla.org/en-US/firefox/addon/1407
Your clips are saved on clipmarks.com and can easily be syndicated to FriendFeed, Twitter, Facebook or saved to your blog.

Not..i will be okay.
It just add ons or feature from mozilla which you can uninstall or disable.
FF is better than IE.
