How can I find out what add-ons I have to update like Shockwave?

I just updated Firefox and Java and I know that I have other updates that I need for Mozilla. I know that Shockwave needs to be updated and Adobe. I was able to view it before the Java update...I was redirected to your site to show me what I needed to update. I just wanted to know how to get there to update my Mozilla please. Thank you!
