More Firefox links in the menu >>
Firefox offers better security, faster browsing, more options, and many other advantages that I have detailed here in the past. However, Mozilla and switch2firefox.com now do a much better job telling you why and how to install Firefox, so I'm leaving that job to them. :-)
There's actually very little to learn to start using Firefox. Your intuition is all you need to switch from another browser. Getting the most out of Firefox requires a little discovery though. A good place to start is the "Learn Firefox" website.
Firefox "clean install": Firefox is usually very stable, but it can out of whack, especially if you experiment with it a lot like I do. ;-) There are two ways to fix Firefox problems though. The quick way is to just create a new profile. If that doesn't work, a "clean install" is in order. There are plenty of instructions for that on the Web. Don't forget to at least save (and later restore) your existing bookmarks.html file if you want to keep your Firefox bookmarks (favorites).

You may instead/also find a Mozilla folder that you need to delete in C:\Documents and Settings\{your Windows user name}\Local Settings\Application Data\Mozilla\.
Firefox extensions can open Firefox to more avenues of attack. (If you stick to extensions from mozilla.org or mozdev.com the risk is minimal.) "Worst Browser Threats May Not Be Security Holes" | EarthWeb
