The bookmarklet currently loads a script from //css-tricks.github.io/The-Printliminator.... This works when relative to an https:// URL and even when relative to an http:// URL, but when viewing, for example, HTML help files on your own machine from file:///C:/local%20content... it tries to load the script from file:///css-tricks.github.io instead of the CDN and fails.
That protocol-relative URL would be useful if this was originally deployed on an insecure page, and later github.io updated to serve it from an https:// domain, but it's 2024. Serving the script over HTTPS works when running the bookmarklet from another https site, from an http site, or from a file:// site, so there's no reason not to use it everywhere.
Please change the bookmarklet from:
loadScript('//css-tricks.github.io/The-Printliminator/printliminator.min.js'
to
loadScript('https://css-tricks.github.io/The-Printliminator/printliminator.min.js'
to make it work on local files.
