> "Suspending unused tabs"

I'm curious to see how aggressive this is. If it's good enough to render my tab suspender extension obsolete, that'd be fantastic.

This really needs to be an OS-level toolkit thing, like on iOS. It's nutty to have applications inspecting system memory use to figure out if they should take pressure off. Ideally I'd be able to suspend entire desktop sessions and all the applications in them, then open a new, clean one, then go back to the old one later. Task-based (work, vacation planning, book research, et c.) GUI session suspend/resume is my #1 most-wished-for feature for a desktop OS but it needs that basic app-suspension support, integrated by the app makers themselves, to work.

This. In the meantime, I'll settle for a real session save/resume in MacOS. I have to reboot often and "restoring" is a mess.

It's in the config parameter's name: browser.tabs.unloadOnLowMemory. Boolean, works only on Windows for now.

Ah man. Hope this makes it to Linux and especially OSX soon!

On Linux, I use cgroups to restrict memory usage of certain applications to prevent them from crashing the whole system.

Any idea when Linux will be supported?

I'm using the Auto Tab Discard extension for now, but having a native way to handle this for Linux users would be great.

On Chrome, i use the Great Suspender which does the trick.

It's the ONLY extension that i keep there.

Great to see it's built-in Firefox.

Somewhat eerie.. I recently installed a tab suspender because a tab crashed or lagged out so I killed its process

This version of Firefox is obviously because of me :P
