I want to save the state of tabs in Firefox or Google Chrome so that I can restore it later by writing a custom add-on / plugin / extension.
The closest I can find is the Firefox Session Storage API , which can save form data and scroll position. However, I want to keep Javascript state as well. Also, if possible, I want to be able to restore the page, even if the website is no longer available. It would be better if there was a way to preserve the entire analyzed resource / data structure.
Is this possible for any of the major browsers?
