Browser plug-ins like Flash and Java add additional features web pages can use. However, they can also slow things down when in use or add extra security holes, particularly in the case of Java.
Each web browser has a built-in way to view your installed browser plug-ins and choose which are enabled, although this feature is hidden in many browsers. To remove a plug-in completely, you’ll need to uninstall it from the Windows Control Panel.
Google Chrome
Google Chrome has several hidden chrome:// pages you can access. To view the plug-ins installed in Chrome, type chrome://plugins into Chrome’s address bar and press Enter.
This page shows all the installed browser plug-ins enabled in Google Chrome. To disable a plug-in, click the Disable link under it. You can also click the Details option to view more detailed information, such as the location of the plug-in on your computer’s file system.
By default, many plug-ins can only run with your permission. This helps prevent websites from exploiting plug-ins like the vulnerable Java plug-in. The Always allowed check box allows you to bypass this protection for an individual plug-in, but it’s unchecked by default for a reason.
Mozilla Firefox
Firefox makes your list of installed plug-ins easier to access. To view your list of installed plug-ins, open the Firefox menu, click Add-ons, and select Plugins.
You can disable individual plug-ins by clicking the Disable button. To view more information about a plug-in, such as its file name, click the Options button. You won’t actually find any options you can use to configure the plug-in from here, only additional information.
Internet Explorer
Internet Explorer lists its browser plug-ins along with other browser add-ons you have installed. To view them, click the gear menu at the top-right corner of the Internet Explorer window and select Manage add-ons.
Browser plug-ins are displayed under the Toolbars and Extensions category, along with any browser toolbars and other type of ActiveX add-ons you have installed. Note that many are hidden by default – click the Show box at the bottom-left corner of the screen and select All add-ons to view them all.
You can disable add-ons by selecting them in the list and using the Disable button at the bottom-right corner of your screen.
