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!
