Usually when I see this from non-spam sites, it's not even pushstate, it's just some page that redirects as soon as it loads. So you press back twice and it goes back -> forwards -> back -> forwards. Disabling pushstate doesn't fix that, it just makes pushstate equivalent to a redirect.

That's relatively easy to work around. Right-clicking on the back button lets you go back several steps at once. I don't know about Chrome, but it does work on Firefox.

AFAICT just holding left-click for half a second has the same effect. That's been my go to since the little triangle dropdown vanished from the back button (checks watch).. uh, some time in the nineties mebe?

Firefox had it in 2010. I don't remember when IE ditched it.

I haven't had that problem in a while. Did browser vendors already do something about it?

On qutebrowser I type 2H instead of H, and it doesn't go to the most recent history item at all. Mostly though, no, spammy websites still do this, and browser's haven't fixed it.
