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/WebKit 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

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.

User Agent Changer

Select ToolsChange Browser Identification to get a menu that allows you to change the User Agent string without going through the Settings dialog procedure.

The plugin allows you to change the Browser and Operating System identification on a domain-by-domain basis. This is useful when browsing websites that limit access to those using a particular web browser.

Default Identification

The default User Agent header for Konqueror is Mozilla/5.0(compatible;Konqueror/4.7)(KHTML/4.7, like Gecko). If you come across a site that refuses this browser access, change your User Agent to one of the options below.

Browser submenu

The following menu items show a list of popular browsers such as Firefox, Internet Explorer, Netscape Navigator, Opera, Other, and Safari.

Apply To Entire Site

This option allows you to specify that the defined User Agent applies across every page on the site you are visiting.


Selecting Configure opens the settings dialog and allows you to fine tune the amount of information you wish to reveal about the browser and operating system being used.

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.
