Classic mode for Wikipedia v1.5.2
Each time you'll visit a Wikipedia page or article, you'll be automatically redirected to its classic layout version (i.e. before the January 2023 interface changes). It does not require to have a Wikipedia account. Simply disable or uninstall this add-on if you want the new interface back.
This add-on is non-commercial and will stay this way. It respects your privacy, and does not retrieve or send any data anywhere (and never will). You can find additional information about the add-on on https://jeanbaptisteb.github.io/classic_wikipedia/.
The add-on also works with other Wikimedia projects: Wikimedia Commons, Wiktionary, Wikisource, Wikidata, and MediaWiki. It leaves Nostalgia Wikipedia untouched.
Its source code is publicly available to anyone to read and reuse for free. Feel free to report bugs, suggest improvements, or even contribute directly to the code on Github!
