Navigation popups is a script, written in JavaScript (source), that offers easy access to article previews and several Wikipedia functions in popup windows which appear when you hover the cursor over links.

  • Quick installation: Enter Special:Preferences and click "Gadgets", check the box to enable Popups, then click save. Follow the instructions on the page to bypass your browser's cache.
  • Other installation method: add the following code to your monobook.js (or equivalent file if you use a different skin). See below for full installation instructions:

If you're having trouble, you may like to peruse some frequently asked questions.

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

The next step is to add <source lang=javascript> {{subst:navpop}} </source> to your monobook.js page. This will add the following code to your .js file: <source lang=javascript> // User:Lupin/popups.js importScript('User:Lupin/popups.js'); </source>

Note: If you are using a skin other than MonoBook (the default), the relevant file you will need to edit is listed below.

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

This tool generates "popup hints" when you hover the mouse pointer over active links and images.

Many of the most important features can be used from the watchlist.

  • hover over a diff link to show a summary of the difference that edit has made
  • hover over a link to an article version to show a short excerpt of the version

There should also be some "navigation links" which access many functions including one-click reversion, editing that page and so on. These may appear in the popup itself, or may be hidden in an "actions" menu depending on your browser and your settings.

In normal articles:

  • hold the mouse over links pulls up a short excerpt of the linked-to article, then hover over the actions link if necessary to see more commands
  • if you hold the shift key then you can drag the popup around

Configuration (optional)

Changing the appearance of your popups

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 for most people, the file to edit is monobook.css.

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.

<source lang=css> .navpopup {

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

} </source>


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

option = value;

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

<source lang=javascript> // User:Lupin/popups.js - please include this line importScript('User:Lupin/popups.js');

simplePopups=true; popupAdminLinks=true; </source>

*Default values are listed in bold

More options may be added, and requests for more configurability are welcome.

Advanced customization

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:

<source lang=javascript> // initialize the array - only do this once extraPopupFilters=[];

// define the function function popupFilterHtmlTable (wikiText) {

 if (/<table/i.test(wikiText)) return '<table>';
 else return ;


// add the function to the array (you can repeat this for lots of functions) extraPopupFilters.push(popupFilterHtmlTable); </source>

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).

Browser problems

Mozilla Firefox

If a user on Mozilla 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 current version reportedly gives correctly functioning menus.


Older versions of Opera have bugs which prevent the menus from functioning correctly. Using a current version (9.0 or higher) should give correctly functioning menus, but you may still experience problems sometimes, with popups not loading, or not disappearing after the mouse is moved away.

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