I want URLs of a page to stay the same no matter where I scroll, including on Discourse where stopping at a certain comment changes the url to that comment’s number. Scroll this page to see: https://meta.discourse.org/t/should-url-change-as-you-scroll/55302
I would check out some of the add-ons for Firefox, Chrome, etc. that disable HTML5 auto play. Might give you an idea of where to start in blocking the pushstate function which is what is used to change the URL as far as I know.
