It will take all memory and crash before that, even with tab unloading. While new FF consumes more memory than the old one, with large number of tabs it still scales waaaaaaay better than Chrome - try opening 500 tabs on Chrome.

It is still experimental, despite being released on stable branch. Old FF is really slow once you get to a large number of tabs. New engine allows it to scale with the number of CPU cores, something which wasn't happening before.

Quantum can potentially become better than the old FF. That said, here is what you have to keep in mind: Actually, anything with autoupdates will cause that, so it is partially the users fault too for leaving it on. People lost entire sessions, hundreds of tabs, extension settings. I am amazed at the blatant disregard for user experience at Mozilla - they decided to mess up all of the users configurations without saying anything in advance. It was written from scratch with a completely new engine, and old extensions do not work with it.
