Can't find a definite answer online. Does Safari put the idle tabs to sleep or not? I know most Chromium based browsers do.
Got a tip for us?

The default configuration is Background Tab Suspension disabled.
returns "does not exist"
Code:
defaults read ~/Library/Containers/com.apple.Safari/Data/Library/Preferences/com.apple.Safari.plist WebKitTabSuspensionreturns "does not exist"
I am not very technical, but I assume that was a no, thank you! 😀
Im trying to see if it's worth moving to Edge for example?
Installed Firefox, noticed a massive memory consumption, won't open it again! 😀

I found this thing a funny example of how Safari is handling active vs inactive tabs.

Thank you! Maybe you also know a way for Mac Mail not to show inline attachments? As in preview the 1 page documents in body? 😀 There is a command online, but it don't work any more 🙁 Big Sure and Monterey seem to have changed.

This does sadly not exist anymore!
I cannot find it in the Debug menu, and also not within the defaults file:
Code:
$ defaults read ~/Library/Containers/com.apple.Safari/Data/Library/Preferences/com.apple.Safari.plist | grep -Ei '(background|suspend)' | grep -i tab
$No result for anything related to background or suspend for Tabs ...

Might be fixed in the future.

If you are referring to the Debug menu, it is not intended for regular users.
You can turn it on as explained in post #5 or with Onyx https://titanium-software.fr/en/applications.html

As the option is no longer present in the menu, I doubt this will have any effect.

Safari is no longer updated on Monterey.
Consider using Orion https://kagi.com/orion/
It has options to suspend tabs.
