QuickDiff lets you quickly view (hopefully) any diff link on a wiki, whether on Recent Changes, Wiki Activity, history pages, the diff view itself, or elsewhere.
Note this will only work for links to the same wiki you're currently on (for example, a diff link on a page at community.wikia.com for a page at dev.wikia.com will load normally, rather than in QuickDiff).
QuickDiff was originally based on the 'DiffAnchored' script, written by Gguigui1, though it has since completely diverged. If you notice any issues or would like to give feedback, leave a message on the talk page. If you can contribute a translation, it'd be very much appreciated!
For personal use, add the code snippet below to your global.js page (for use on all wikis) or your common.js page on your wiki (for use on a single wiki). Note that personal JS must be enabled for your account.
Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
