This page will wreck your browser history. The post explains the rationale at the end, but frankly speaking there should have been the warning for each checkbox.
Your comment made me realize that there are people who curate their browser history (other than just removing problematic stuff). Not criticizing, just never considered that was something anyone cared about.
If you curate your browser history, this is an easy fix. This is more of a problem for people like me who occasionally check their browser history because they want to revisit a site they were on recently.
Not tackling the same problem but in the spirit of removing things and Firefox, you can bring up a url in the address bar, press down arrow, press Delete, and it'll go away
It only deletes that very specific url though, like foo.com, however foo.com/bar will still exist
I’m on mobile. The checkboxes had no effect, the code run on its own by default. And I gave up on trying to go back to Lobsters by using the Back button.
It actually just updates window.location.hash instead, which does cause a flood of history entries (looks like just one per distinct animation state, though, at least in Chrome). See the "One Last Thing" section near the bottom of the article for the rationale. See the inline code snippets in the article, or view source for wavyurl.com to see the actual code used.
