You must have a user account to install and use the Navigation popups feature. If you do not have an account, you will need to create one and log in.

Automatic installation
  • Go to My Preferences / Gadgets / Browsing gadgets, check "Navigation popups", and click Save.
Manual installation
// [[User:Lupin/popups.js]]

Note: the link above is to skin.js, which should take you to the correct page if you have JavaScript enabled. For reference, the relevant file you will need to edit is listed below.

Installation on remote MediaWiki installations

Add the following to your user script file:

// [[wikipedia:User:Lupin/popups]]

After saving the page, clear your browser's cache (on Internet Explorer Ctrl+F5; on Mozilla Firefox Shift+Ctrl+R; on Opera F5). Assuming that you have not disabled JavaScript in your browser, a popup should appear whenever you hover your mouse over an internal link in Wikipedia. If you use more than one web browser, or more than one PC, you may need to clear the caches for each so that the popup appears.

To install the script on the Commons or Wiktionary, repeat this procedure on those wikis.

To uninstall the script, delete the above lines from the same page and clear your browser's cache.

Usage guide[edit]

This tool generates "popup hints" when you hover the mouse pointer over active links and images. These popups provide information about the link's target and give quick access to a number of relevant actions.

If you hold the shift key then you can drag the popup around.

Popups depend on the type of link:

  • Links to ordinary articles: popup provides a preview of the first paragraph and image of the article; the Actions menu allows to view the History and Talk page of the article, to edit and watch the article etc.
  • In the edit box: Highlight a [[wiki link]] to get an article popup.
  • Diff links: On history or watchlist pages, hover over diff links like "(cur)" or "(prev)" to get a summary of the difference; the Actions menu allows you to revert or undo the edit.
  • User: links: information about the status of the user; User menu gives access to Talk page, recent contributions etc.
  • Image links: information from image's description page
  • In popups: most of the links in popup windows will open new popups when hovered over.

Configuration (optional)[edit]

Changing the appearance of your popups[edit]

By editing your user CSS file, you can change the appearance of the popups. Your user CSS file has exactly the same name as the javascript file, but with "css" instead of "js" at the end. So you should edit your current skin's .css page.

Here is an example which gives an orange-flavoured popup with a border and changes the font used. This makes the popups look pretty silly, but it shows the sort of thing you can do if you feel like it.

.navpopup { 
  background-color: #FFBE20  !important;
  font-family:      serif    !important;
  color:            #404     !important;
  font-size:        medium   !important;


There are some options that you can set. To do so, edit your user javascript file and add a line of the form

window.option = value;

where option and value are chosen from the table below. For example, to turn on extensive menus and turn on admin links, you need to add something like this in your javascript file:

window.popupStructure = 'menus';
window.popupAdminLinks = true;

Advanced customization[edit]

Adding filters[edit]

You can define custom filters for articles. These are javascript functions which are run after the page statistics are generated, and their output is appended (as HTML) to that part of the popup. (Note that if simplePopups is true or popupSummaryData is false, then nothing will be displayed).

The way to set this up is to write a filter function which accepts a string (the wikitext of the article) as input, and returns a fragment of HTML. Repeat for as many filters as you want, and then create an array extraPopupFilters which contains all of the functions, in the order in which you want them to be run.

For example, let's say you want to be told whenever the wikitext of an article contains a table written using HTML tags rather than wiki markup. One way to do this is to add the following to your user javascript file:

// initialize the array - only do this once
window.extraPopupFilters = [];

// define the function
function popupFilterHtmlTable (wikiText) {
  if (/<table/i.test(wikiText)) return '&lt;table&gt;';
  else return '';

// add the function to the array (you can repeat this for lots of functions)

Then when a popup is generated for a page containing an HTML table, you should see <table> in the popup. (It may also appear for other pages, such as this page. Correcting this defect is left as an exercise for the reader).

Other examples[edit]

If you want to enable popupRedlinkRemoval, popupFixRedirs and popupFixDabs features in all pages except the special ones, histories and previews (where those features are obviously useless) you can add this lines

// Normally features are enabled
var toFix = true;

// In special pages, histories and previews disable them
if (wgCanonicalNamespace == "Special" || /*
    */ location.href.indexOf('&action=history') != -1 || /*
    */ location.href.indexOf('&action=submit') != -1)
  toFix = false;

window.popupRedlinkRemoval = toFix;
window.popupFixRedirs = toFix;
window.popupFixDabs = toFix;

to your user JavaScript file.

Browser problems[edit]

Google Chrome[edit]

If the user is using the Virtual Keyboard (by Google)extension, the popups may sometimes appear in the wrong locations, sometime off the screen entirely. Frequently, popups appear in the same location as the first, leading to a several overlapping popups since the pop-ups do not disappear even when the mouse no longer hovers over a link. This conflict with popups is present as of Version of the Virtual Keyboard extension.

Internet Explorer[edit]

Pages with "–" in their titles will not display correctly in the popups. This bug does not exist in Internet Explorer 9, so upgrading will fix the bug.


If a user on Firefox with the Adblock Plus extension installed cannot see the popup, only the normal tooltip, Adblock Plus may be blocking the operation of navigational popups. This can be solved by adding an exception to the filtering rules – go to the Main Page, right click the icon in the status bar and check Disable on


The menus do not function correctly in some older releases of Safari. Using a version 3 or higher is supported.


Using a current version (11.0 or higher) should give correctly functioning popups. Using an earlier version, you may experience problems, such as popups not loading or not disappearing after the mouse is moved away.

This tool should not be affected by any browser popup blocking settings.
