If you want it sitewide, you should put it in your MediaWiki:Common.js, however, you don't have JavaScript enabled, so you'll need to request that at Special:Contact/general. If you just want it for you personally, you can put it in your personal Common.js. Make sure you enable personal Javascript in your Special:Preferences. I hope that helps!
