Firefox Quantum About:Config Tricks You Need to Learn

I'm curious about "Lower Memory Usage When Minimized". Is there a downside to this? Why wouldn't this be a default setting?

Details: This tweak is mainly for Windows users. When you minimize Firefox, it will send Firefox to your virtual memory and free up your physical memory for other programs to use. Firefox will reduce its physical memory usage, when minimized, to approximately 10MB (give or take some), and when you maximize Firefox, it will take back the memory that it needs.

The preference name does not exist and needs to be created.

Right-click on the background and select “New -> Boolean.”

Enter the name when prompted: config.trim_on_minimize.

Enter the value: True.

They're referring to an experiment conducted some time ago (not in the current Nightly). They've pushed a pref switch for some users and gathered some memory data.

Hi TyDraniu,

Thanks, very interesting. The article mentions "people who had tab unloading enabled were able to use the browser for longer periods of time". Are they strictly referring to a setting in the current Nightly, or is there something I'm missing?
