Wikipedia:Tools/Navigation popups

From Wikipedia, the free encyclopedia
Navigation popups Icon
Navigation popups in action. In this screenshot, the user is hovering the mouse over a link to the encyclopedia article.

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"; under the "Browsing" section, check the box to enable "Navigation popups: article previews and editing functions pop up when hovering over links", then click save. Follow the instructions on the page to bypass your browser's cache.
  • Other installation method: add {{subst:navpop}} to your current skin's .js page. 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 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

This is the preferred method of enabling Navigation popups

Manual installation

Alternatively if you wish to add this to a specific skin rather than a file that works for all skins (as above), then

// [[Wikipedia:Tools/Navigation popups]]

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, or via your global.js

Add the following to your user script file:

// [[Wikipedia:Tools/Navigation 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

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)

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 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;
Configuration options
Option Values
Default in bold
popupDelay 0.5, a decimal number The number of seconds before popups appear.
popupHideDelay 0.5, a decimal number The approximate number of seconds between the mouse leaving a popup and its disappearance.
simplePopups true, false If you just want the links or find the amount of bandwidth consumed too great, then set this to true. No data will be downloaded and the popups will just consist of a list of links.
popupStructure 'original', 'fancy', 'fancy2', 'menus', 'shortmenus', 'lite', 'nostalgia' Select the structure of the popups – view examples here. The 'original' setting, which is the default if simplePopups is true (or if your browser is known not to support menus), has all the navigation links in the popup itself; 'nostalgia', 'fancy' and fancy2 are variants of this. The 'shortmenus' setting, which is the default if simplePopups is not true, puts the navigation links in popup menus which appear when you mouseover the links beside the popup title. 'menus' is a more extensive version of 'shortmenus' with more links. Finally, 'lite' is a very simple structure, with just the preview and no navigation links at all.

Note that to set this variable, you need to include the single quotes, e.g. popupStructure='fancy';.

popupActionsMenu true, false When using menus, you can either have the title link in the popup generating a menu (if this is set to false) or a separate "actions" menu (if this is set to true, the default).
popupAdminLinks true, false Links to block people, delete pages and protect or unprotect pages are by default only available to administrators. Use this variable to override the default behavior.
popupShortcutKeys true, false If this variable is set to true then you can focus some of the links in the popups quickly by pressing keys. When you hover the mouse over a link with a shortcut, the shortcut key appears at the end of the popup hint. For example, in Firefox or Opera, to quickly edit an article in a new tab you can type 'e Control-Enter'. Pressing escape should hide the popup, too.
popupHistoricalLinks true, false When hovering over links to old revisions and diff links, extra links such as "editOld" are generated if this is true. Otherwise, you get the same links as when hovering over an ordinary link.
popupOnlyArticleLinks true, false If true, then popups are only generated for links in the article. Otherwise, many other links (such as Edit, Help) get popups too.
popupMaxWidth 350, an integer or false The maximum width of the popup in pixels. Setting this to false means the popup will expand to accommodate its contents.
popupInitialWidth an integer or false The initial width of the popup in pixels. Setting this to false means the popup will initially be the size needed to accommodate its initial contents.
popupTocLinks true, false Whether or not to create popups for the Table of content items. Set true to create popups for table of content.
popupSubpopups true, false If this is true then popups are generated for links in previews.
popupDragHandle false, 'popupTopLinks', ... The name of an element by which the popup can be dragged without holding the shift key. If false, then the popup can be dragged using the shift key instead.
popupAllDabsStubs true, false If this variable is set to false then only pages that look like stubs or disambiguation pages in the article namespace are treated specially. (Setting this to true can lead to lots of false positives).
popupAdjustDiffDates true, false If true, then dates in history, diff and user contributions previews are adjusted according to the settings in your user preferences.
popupModifier false (default), 'ctrl', 'shift', 'alt', 'meta' Lets popups only appear when pushing a modifier key while hovering over the links. This prevents unintentional popups that hide page content.
popupImages true, false If this is false then images are never displayed.
imagePopupsForImages true, false By default, preview images are loaded even when hovering over visible images. Setting this to false turns that off.
popupThumbAction "imagepage", "sizetoggle", "linkfull" This controls what happens when you click the image in a preview. "imagepage" takes you to the image page (and will generate a subpopup when you hover over the image), unless the popup is generated for the image page; "sizetoggle" means the image size is toggled on click, and "linkfull" means that the image links directly to the full size version.
Redirs, Dabs, Reversion
popupFixRedirs true, false If this variable is set to true then you can automatically "fix" links to redirect pages by clicking on the "Redirects" link. Note: you probably don't want to "fix" such links every time you come across them, and you definitely don't want to go on a hunt for them to "fix" them. See About fixing redirects.
popupRedirAutoClick 'wpDiff', 'wpPreview', 'wpSave' The button which is automatically pressed when fixing redirects.
popupFixDabs true, false If this variable is set to true then you can automatically "fix" links to disambiguation pages by clicking one of the links at the very bottom of the popup.
popupRedlinkRemoval true, false If this variable is set to true then you can automatically remove links to non-existent pages (so-called "red links") by selecting "Remove this link".
popupWatchDisambiggedPages true, false, null If this variable is set to true then fixed dab pages will always be watched; if it's false, then they'll always be unwatched. If it's null, then the page will be watched or unwatched according to the settings in your user preferences.
popupWatchRedirredPages true, false, null If this variable is set to true then fixed redirect pages will always be watched; if it's false, then they'll always be unwatched. If it's null, then the page will be watched or unwatched according to the settings in your user preferences.
popupNavLinks true, false If this is true then navigation links are displayed. If false, then these are switched off.
popupLastEditLink true, false Whether the popup should contain a "most recent edit" link.
popupEditCounterTool "supercount", "custom" The edit counter tool to use or a custom url defined by popupEditCounterUrl.
popupEditCounterUrl "" The url for a custom edit counter. You can use replaceable parameters in this url: $1 will be replaced with the username, and $2 with the database name (for example, enwiki_p).
Previews, etc.
popupPreviews true, false If this is true and you haven't set simplePopups, then a preview of the first part of the article will appear. (Reports of pages for which this is done badly are most welcome). If false, then this is switched off.
popupSummaryData true, false If this is true summary data for the target page is displayed. If false, then this is switched off.
popupLastModified true, false If true then the age of the page is displayed in the summary data. This is the amount of time that has elapsed since the article was edited.
popupDiffDates true, false If true, the dates of the revisions being compared are shown when previewing diffs.
popupOnEditSelection true, false, 'cursor', boxpreview If this is true then popups are generated for selected wikilinks when editing.
popupImageLinks true, false If true, pages linking to an image should appear in the preview. This currently does not work for commons images.
popupShowGender true, false If true, a gender symbol is displayed in popups showing user info.
Edit summaries [edit]
popupRevertSummaryPrompt true, false If true, you will be given the chance to change the default revert summary with each reversion.

Advanced customization

Adding filters

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

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 these lines to your user JavaScript file:

// Normally features are enabled
var toFix = true;

// In special pages, histories and previews disable them
if ( mw.config.get( 'wgCanonicalNamespace' ) === 'Special' ||
	$.inArray( mw.util.getParamValue( 'action' ), [ 'history', 'submit' ] ) !== -1 )
	toFix = false;
window.popupRedlinkRemoval = toFix;
window.popupFixRedirs = toFix;
window.popupFixDabs = toFix;


Please see this page for translations of the script interface and of this page into other languages. You'll also find instructions for creating a translation yourself.

Browser problems

Google Chrome

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 several overlapping pop-ups 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

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
Firefox Addon - Linky may try to open all the extra links - e.g if viewing Special:NewFiles (100 files), and one selects "Open all image links in tabs", it often tries to open 400 odd links.


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.
