You can still do things like being able to get the battery status with JS or detect visited links.

  > detect visited links Is this still possible? I was under the impression this is prevented in most browsers.

      For firefox there is dom.battery.enabled and https://developer.mozilla.org/en-US/docs/Web/API/Battery_Status_API https://developer.mozilla.org/en-US/docs/Web/API/Battery_Sta... but it seems that since 42 it is enabled only for addons. It seems that I was wrong about that indeed.

    Well, browser vendors keep adding features, and in 2014, it was predicted by lcamtuf that the mix-blend-mode property would be useful to access browser history: https://lcamtuf.blogspot.fr/2016/08/css-mix-blend-mode-is-bad-for-keeping.html https://lcamtuf.blogspot.fr/2016/08/css-mix-blend-mode-is-ba... Two years later, it was implemented, and the demo seems to be working here in Firefox 56: http://lcamtuf.coredump.cx/whack/ http://lcamtuf.coredump.cx/whack/

  Newer versions (since around 2013) of webkit and gecko limit a:visited style changes to just colour or background colour. So the getComputedStyle() trick doesn't work anymore. Is that what your referring to?
