Super cool but I did get this error while scrolling the timeline on safari/iOS

Application error: a client-side exception has occurred while loading jivx.com (see the browser console for more information).

Same on Firefox/Linux

Yep, seems to refer to "SecurityError: Attempt to use history.replaceState() more than 100 times per 10 seconds"

I hate the History API especially pushState. Even with this limit of 100 times per 10 seconds it still pollutes my browsing history too much. I need to vibe code an extension that makes pushState/replaceState noops on all webpages.

Seems like you hate the abuse of the API more than the API itself. For Single Page Apps it makes sense to support the Back button by, based on merit, populating the history synthetically

Then you'll discover many pages are SPAs in disguise.

Such as?

Because joke’s on you, my browser gets so slow that I know when a page is a SPA, even when it uses History API.
