title: MediaWiki removed MathJax. Can MathJax be forced on client side another way?
body: <p>Much to my displeasure, MediaWiki has <a href="https://www.mediawiki.org/wiki/Extension:Math#Client-side_rendering_with_MathJax" rel="noreferrer">recently disabled support for MathJax</a> (ticket: <a href="https://phabricator.wikimedia.org/T99369" rel="noreferrer">T99369</a>) rendering of TeX formulae wikipedia-wide.</p>
  
  <p>Since me (and others, if you skim the ticket's discussion thread) find the rendering with the remaining options (MathML, PNG) inferior, I would like to "slipstream" MathJax into Wikipedia.</p>
  
  <p>Since loading further JavaScript files directly via the custom JavaScript settings in Wikipedia does not seem possible using <code>&lt;script&gt;</code> elements, I am at a loss on how to achieve this feat. Would it be, MathJax could be included via CDN most easily.</p>
  
  <p>I am using current Edge and Firefox browsers, so any solution working with one or both of them would be greatly appreciated!</p>

  <p>Meanwhile, I found Greasemonkey for Firefox, which might be able to accomplish this, given a suitable script. Since I am neither a Greasemonkey-, nor a JavaScript-expert, any hint on how to proceed to write such a script would be helpful.</p>
