This has been the case for a long time, I just googled and first hit was an article from 2008. source: http://www.ghacks.net/2008/07/09/change-the-session-stor

  Wikipedia claims the session restore features was added with 2006's 2.0 release. That's what I would have guessed, since that release was (famously) a giant step backwards in performance, which was never really addressed except by waiting for hardware to improve. I'm holding out hope that whoever's responsible for Firefox abandoning "good, light, cross-platform web browser" as its differentiator stays away from Servo, at least for a while. That's a niche that's unserved currently, AFAIK.
