How to save a tab's memory state in Firefox/Chrome?

Question

I want to be able to save a tab's state in Firefox or Google Chrome so that I can restore it later, through writing a custom add-on/plug-in/extension.

The closest thing I can find is Firefox's session store API, which can save form data and scroll position. However, I want to save Javascript state too. In addition, if possible, I want to be able to restore the page even if the website is no longer available. It would be the best if there a way to save all the parsed resource/data structure.

Is it possible for any of the major browsers?

Try using Session Buddy: https://chrome.google.com/webstore/detail/session-buddy/edacconmaakjimmfgnblocblbcdcpbko. I've been using it for a while now, and it does exactly what you're talking about and more.

Does that also save the state inside closures? – bigblind Dec 05 '13 at 17:35

@shswanson, No it doesn't. **It only saves and reload URL.** It's the URL and nothing else. – Pacerier Feb 21 '17 at 12:05

Just serialize everything you need to restore your page state into a localStorage (it is persistent, unlike sessionStorage) and invoke a respective deserialization function in your page's DOMContentLoaded (or load) event handler.

Yea, but u can't use it as a general purpose way for *other* 3rd party sites. – Pacerier Feb 21 '17 at 12:05
