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)
