It's been a relatively quiet day so I thought I'd mention this nice little tool that Mozilla has released:

https://www.mozilla.com/en-US/plugincheck/

It does exactly what it looks like - checks to see if your plugins are up to date and provides links to update them if they are not. It works with Firefox 3.6+, Opera 10.5, Safari 4, Chrome 4, or IE 8 and while they claim limited support for IE, it worked just fine when I tried it.
