Konqueror Plugins

Konqueror Plugins

KDE releases several useful plugins that interact with Konqueror in various ways. These are explained briefly below.

Use SettingsConfigure Extensions... to open a dialog with all installed plugins and select the ones you need. All plugins are accessible in the Tools menu.

Only plugins appropriate for the current mode (file manager or browser in KHTML/WebEngine view) are listed in the dialog.

Browser Mode

Web Page Translation

This uses the machine translation service provided by Google Translate to translate the current HTML page to whatever language you want (within reason). It can be launched with ToolsTranslate Web Page.

If you have a portion of the text on the page selected, that will be translated instead of the entire URL.


Machine translation is not a perfect science! Google will at best give you a rough translation, and at worst will give you a very funny read. Don't base important decisions on things you have read from a Google translated page, without confirming that the translation is indeed accurate.


You may only translate web pages that are accessible on the world wide web. To translate any other text, you should go directly to the Google site itself, where you are able to paste in text for translation.

DOM Tree Viewer (KHTML view only)

The DOM Tree Viewer allows a developer to view the styles, attributes and elements of a web document.

Selecting ToolsShow DOM Tree opens a new window which displays the document object model (DOM) of the current HTML page.

By default the display starts at the root node of the document, example: documentElement, all other nodes that you will see are children or descendants of the root node.

If you wish to manipulate the DOM tree in any way you will have to use an external script to do so.

Web Page Validator (KHTML view only)

This plugin uses the W3C HTML validator to validate the current page, very useful when creating web pages.

Validate HTML (by URI) / Validate HTML (by Upload)

The validate HTML option allows you to compare your HTML document to the defined syntax of HTML and reports any errors found. Validating your HTML will ensure that your pages display properly on all browsers.

Validate CSS (by URI)

Allows you to validate your CSS style sheet that is embedded in an HTML or XHTML document. Having valid CSS is critical to ensuring that your web site maintains a consistent look regardless of the browser that is being used.

Validate Links

Allows you to confirm that the links on your site contain no redirects or broken links. This tool recursively checks all links on a site.

Validate Page

Validates the current page but does not show the result in another window or tab as the previous actions. Using this item enables the action View Validator Report to display a summary of the validation.

Configure Validator

The configure validator item allows you to view the preset validators you can use to validate your HTML and CSS.

HTML Settings (KHTML view)

Select ToolsHTML Settings to enable or disable a number of HTML settings without going through the Settings dialog.


Allows you to turn the use of JavaScript in Konqueror on or off.


Allows you to turn the use of Java™ in Konqueror on or off.


Allows you to turn the use of Cookies in Konqueror on or off.


Allows you to turn the use of the Konqueror plugins you have installed on or off.

Autoload Images

Allows you to turn on or off the loading of images in web pages.

Enable Proxy

Allows you to enable or disable the use of a proxy in the Konqueror browser.

Enable Cache

Allows you to enable or disable the use of a cache in the Konqueror browser.

Cache Policy

The Cache Policy submenu provides you with a way to configure how Konqueror uses a cache. The possible uses include:

  • Keep Cache in Sync

  • Use Cache if Possible

  • Offline Browsing Mode

Archive Web Page (KHTML view only)

Invoked with Tools Archive Web Page, this tool creates an archive (.war ) file containing the web page being viewed including the images. Left click on the archive file name to view the saved page.

Auto Refresh (KHTML view only)

This works on any readonly part (though currently it only plugs into khtmlpart). It lets you tell Konqueror to refresh a page automatically after a specific period. This is useful for things like news pages, and should be very nice for people using Kiosk mode

Minitools (KHTML view only)

This plugin adds implementation for so-called bookmarklets. Bookmarklets are little Javascript programs which can be saved and used like normal web page bookmarks. Therefore, they are simple one-click tools that can add substantial functionality to the browser.

Document Relations (KHTML view only)

Displays the document relations of a document

File Manager Mode

Directory Filter

This is controlled by ToolsShow Filter Bar (Ctrl+Shift+I) and allows you to choose which types of item are displayed in a folder.

Image Gallery

In File Manager mode, you can select ToolsCreate Image Gallery or use Ctrl+I to create an HTML page with thumbnails of all the images in the current folder. By default the HTML page is called images.html and the thumbnails are put into a new images folder.

When you start the Image Gallery plugin a dialog opens allowing you to adjust the way the gallery is created.

The Look dialog is for adjusting the appearance of the gallery page.
Page title

The Page title option has a text input box for changing the title of the image gallery page.

Recurse subfolders

The Recurse subfolders check box enables recursing of subdirectories. If the check box is enabled, a slider and spin box are enabled to select the recursion depth.

Copy original files

The Copy original files check box creates an image folder storing copies of the original images used in the gallery.

Use comment file

The use comment file check box enables a file selector to choose a comments file to use with your gallery. The comment file contains the subtitles for the images.

The format of this file is:

# this is a comment, lines starting with '#' are ignored



The thumbnails dialog is used for adjusting the properties of the thumbnails in the gallery.
Image format for the thumbnails

The image format combo box allows you to choose which format is used for the thumbnail images.

Thumbnail size

The thumbnail size option provides a slider and spin box for adjusting the size of the thumbnails used in the gallery.

Set different color depth

The set different color depth check box enables a combo box for changing the color depth of the thumbnails if you wish to use a different color depth to that used in the original image.

Search Bar

Provides a text box for easy access to search engines such as Google. Clicking on the icon on the left side of the search box opens a menu to select and enable different search engines and configure their Web Shortcuts.

Shell Command Plugin

This plugin enables you to execute a shell command in the current folder and view the output in a separate window.
