In order to try it for different sites, execute the script below on browser address bar.
[[ javascript:(function () { var script = document.createElement('script'); script.src="//cdn.jsdelivr.net/npm/eruda"; document.body.appendChild(script); script.onload = function () { eruda.init() } })();
]] ]
According to [ https://developer.mozilla.org/en-US/docs/Web/API/Document/body#browser_compatibility ], "document.body" did not work in Firefox until version 60. "cdn.jsdelivr.net" seems to redirect HTTP access to HTTPS (via HTTP 301). (so omitting the protocol would be likely pointless; and in some cases erroneous)
"<script ...></script>" used instead of "<script ... />", for some parsers that could not even properly recognize XML.
"(function () { ... })()" structure mostly serves as a clumsy scope hint. (preventing "x0" polluting the outer scope)
[ [1]
On certain legacy browsers would have to be:
[[ javascript: (function () { var x0 = document.createRange(); x0.selectNode( document.body || ( document.body = document.getElementsByTagName( "body" )[0] ) ); document.body.appendChild( x0.createContextualFragment( "<script src='https://cdn.jsdelivr.net/npm/eruda' onload='eruda.init();'></script>" ) ); })();
]]
Or perhaps doesn't work whatsoever. (Google query: `Chrome "createContextualFragment" error`) ]

"append" also has similar compatibility issues. (and whose usage is not justifiable there)
[[
javascript: void document.getElementsByTagName( "body" )[0].insertAdjacentHTML( "beforeend", "<script src='https://cdn.jsdelivr.net/npm/eruda' onload='eruda.init();'></script>" );
]]

javascript: (function () { var x0 = document.createDocumentFragment(); x0.innerHTML = "<script src='https://cdn.jsdelivr.net/npm/eruda' onload='eruda.init();'></script>"; document.getElementsByTagName( "body" )[0].appendChild( x0 ); })();
]]
Such 2 (direct "<script>" injection) may not work, for browsers may for "security considerations" reject such.
[[
javascript: void document.getElementsByTagName( "body" )[0].appendChild( document.createRange().createContextualFragment( "<script src='https://cdn.jsdelivr.net/npm/eruda' onload='eruda.init();'></script>" ) );

Further note on "createContextualFragment":
(mostly unverified, and stale)
[[
Error: NOT_SUPPORTED_ERR: DOM Exception 9

https://web.archive.org/web/20230329062158/http://vird2002.s8.xrea.com/javascript/document.implementation.createHTMLDocument.html#Note
Firefox v3.6.6 は, createDocument() の第三引数に [object DocumentType] を指定すると, range.createContextualFragment() 実行時にエラー "uncaught exception" が発生する (原因不明). 第三引数に null を指定すればエラーは発生しない.
Google Chrome 5 は, createDocument() の第一引数 (名前空間) に null を指定して生成した [object Document] において, range.createContextualFragment() を実行すると "Uncaught Error: NOT_SUPPORTED_ERR: DOM Exception 9" が発生する (原因不明). createDocument() で第一引数を指定すれば, エラーは発生しない.
Opera v10.60 は, createDocument() で生成した [object Document] において, range.createContextualFragment() を実行するとクラッシュして再起動を要求される. (原因不明) ]
