I had this problem on my old 2012 with 8GB of RAM and am also having it on my new 2020 MacBook Pro with 16GB of RAM. Okay if I stay on Facebook for a long time I get a low memory error in Safari. This does not always happen but it happens sometimes so its hard to troubleshoot. This may be a browser issue or a facebook issue with Safari. Is anyone else having this problem?

Some webpages can accumulate a lot of memory, especially those that are dynamic, i.e. load additional data over time or keep connections open, e.g. to listen for and deliver notifications, while never really freeing up the memory.

If the memory footprint becomes too significant, Safari may notify you. It does not necessarily have anything to do with the amount of memory your system has; there maybe some threshold programmed into Safari.

Facebook ticks all of the boxes. The solution is to just manually refresh the page.

Okay I will try this the next time I experience the error. Thanks..

What is the solution for this?

Thanks!

If anyone can find a way of turning off this message I'd be very grateful to know. Facebook is the worst for causing it, and the website itself may be crazy resource intensive, but I've got a Mac Pro with 96GB of RAM. I've got plenty of spare memory (including when I'm running half a dozen VMs) and frankly I want that message to go away and never come back!

That message is extremely annoying and does not seem grounded in any reality, as you found on your 96gb machine. I see it on all my Macs including a new Mini with 64gb RAM. It's an issue for me with a web site I'm developing that uses webGL to display LIDAR maps in 3d. I get that message after a minute or two on this site, but NEVER see it with Opera, Firefox, Chrome or Edge.

I really do prefer Safari (although that's just force of habit) but wish Apple would give us a preference to disable this stupid warning. In spite of the warning, I have never noticed any effect on performance on any of my Macs.
