Why is Facebook “Using Significant amounts of Memory”?

When using Facebook in Safari 11.1.2, I’ve been getting a warning that says “This webpage is using significant memory. Closing it may improve your Mac’s responsiveness.”

I’m using a 2017 21” iMac, with 8 gb of RAM, running macOS 10.13.6.

I’ve cleared my caches in Safari, and its History.

It doesn’t seem to be happening when I use Firefox on the same machine.

What’s doing on?

How — in layman’s terms — do I stop this?

iMac, macOS High Sierra (10.13.3)

Just ignore it.


It is an annoying pop up that we all could do without.


A Safari.app feature Apple thinks is useful somehow.
