Old-Arch-Wiki (Chrome extension)

Automatically adds the useskinversion=1 parameter to all Arch Wiki URLs to enable the good old full-width layout.

To install it in Chrome, you need to enable developer mode in chrome://extensions/ and add it there (because to publish it in Chrome Web Store, you need to pay a fee).

This is Chrome version of this Firefox extension.
