How to Update Firefox

There are so many security holes in Internet Explorer that I simply no longer use it. I use Mozilla Firefox instead. While Firefox is a significantly safer browser—we Firefox users don't have to worry about the drive-by spyware and adware installations that constantly plague Internet Explorer users—Firefox is not without its own share of security problems. In fact, in the last eight months or so, there have a BUNCH of vulnerabilities found in Firefox.. Check out http://www.mozilla.org/projects/security/known-vulnerabilities.html if you don't believe me.
That doesn't mean that Firefox is a lousy browser. Rather it just means that, just as you need to update Windows to make sure your computer has all of the latest Microsoft security patches, you also need to update Firefox from time to time.
There are three ways to do this:

1. Download and install the newest version of Firefox.
2. Click on the hidden "Check Now" button inside of Firefox.
3. Click on the red update arrow icon whenever it appears in Firefox.
