Qualys browser checker

Ever since the recent craziness with vulnerabilities in Java plugins, I've making a concious effort to use Qualys's browser checker - https://browsercheck.qualys.com/ - on a routine basis both at home and at the office.

Installing the tool in your browser is very easy, and the service is free and painless to use.  I have been using it to both to determine if my current browser and plugins are up to date, and also to identify plugins that are installed and enabled, but which I don't really need or use (e.g., Silverlight which I often disable for long stretches at a time).

Qualys generates a nice report

like the one above to let you know if everything is up-to-date.
