Your Java version is also outdated. The latest version of Java is Version 6 Update 30. You are running Version 6 Update 14. It is recommended you open Java through your Control Panel...select the Update tab and then click the Update Now button.
Most programs on your computer will require an update along the way. It would be wise to read and understand how to use these programs, as well as how to configure their update features.
I use the Chrome browser, as well as Opera. Not a big fan of Firefox...since it's become a real resource hog and has too many bugs. I also use Internet Explorer and Safari...since I want to know how my site appears to those who may use these browsers.
I highly recommend Chrome. You may want to read this:
