Browser Plugins

Global Settings

The first setting here is Enable Plugins globally. If you disable this check box, then Konqueror will not use any plugins. If you enable it, then any installed and configured plugins that it can find will be used by Konqueror

You can also restrict Konqueror to Only allow HTTP and HTTPS URLs for plugins by checking the box.

The next option determines, if plugins are loaded on demand only.

Use the slider labeled CPU priority for plugins to adjust this setting.

Click the Domain-Specific Settings button to open a dialog where you can set specific plugin policies for any particular host or domain. These policies will be used instead of the default policy for enabling or disabling plugins on pages sent by these domains or hosts.

Add a new policy here or select a policy and use the controls on the right to modify it.



As Netscape®'s Navigator has been a web browsing standard for many years, so-called Netscape® plugins have appeared that allow rich web content. Using those plugins, web sites can contain PDF files, flash animations, video, etc. With Konqueror, you can still use these plugins to take advantage of rich web content.


Netscape® plugins should not be confused with Konqueror plugins. The latter ones specifically extend Konqueror's functionality; they are normally not used to display rich web content.

Scan for Plugins

Konqueror has to know where your Netscape® plugins are installed. This can be in several places, i.e. you might have system-wide plugins in /opt/netscape/plugins and your personal plugins in $HOME/.netscape/plugins. However, Konqueror will not automatically use the installed plugins: it first has to scan a list of folders. You can initiate the scan by clicking Scan for Plugins.

To find plugins, Konqueror will look in the folders specified in the Folders frame. When you use this control module for the first time, this list will already be filled with reasonable paths that should work on most operating systems. If you need to provide a new path, click the New button; then you can either enter the new path in the text edit box to the left, or choose a folder using the file dialog by clicking the Open file icon. As scanning the folders can take a little time, you might want to remove folders from the list where you know that no plugins are installed: do this by selecting a folder and clicking Remove. Using the Up and Down buttons you can change the order in which folders will be scanned by moving the selected folder up or down.

As usual, click Apply to save your changes permanently.


In this section, you can see a list of the Netscape® plugins found by Konqueror, displayed as a tree. Double click on a plugin to fold it out and you will see that the different mime types this plugin can handle will be displayed as branches. Fold out a mime type to see its info.

This list is only for informational purposes.
