Keeping your browser plug-ins up to date will result in a more secure browsing environment. This guide will introduce you to Plugin Check, a simple but yet valuable tool for assessing the status of browser plug-ins in the Firefox web browser.
You won’t need to download or install additional software. Open Firefox and click Plugins to connect the Plugin Check service.
Plugin Check will run a quick scan. It will then display a complete list of all the installed plug-ins as well as their current status (Up to Date, Unknown, Outdated...):
Outdated plug-ins are listed first at the top of the list. Click on the Update Now button to go to the download page(s).
