Memory saver in Chrome

Probably it is possible to enable the "Memory saver" feature in Google Chrome and add sites to "Always keep these sites active" using a Chrome policy or a script.

Here are the steps to achieve this:

1. Create a text file with the following content:

{
"policy": {
"TabFreezingEnabled": false,
"EnableMemorySaver": true,
"EnableAutomaticTabDiscarding": true,
"WhitelistUrls": ["https://example.com", "https://example.org"]
}
}

Don't forget to Replace the example URLs with the websites you want to add to the whitelist.

1. Save the file with a .json extension, for example, chrome_policy.json.

2. Open Google Chrome and navigate to chrome://policy.

3. Click the "Reload policies" button at the bottom of the page.

4. Verify that the new policy has been applied by going to chrome://discards.

5. You can also use a script to apply the policy. Here is an example script:

#!/bin/bash

policy='{
"policy": {
"TabFreezingEnabled": false,
"EnableMemorySaver": true,
"EnableAutomaticTabDiscarding": true,
"WhitelistUrls": [.     ]
}
}'

sudo /usr/bin/defaults write /Library/Managed\\ Preferences/com.google.Chrome.plist Policy $policy

Note:- Replace the exple url

unfortunately, it didn't work for me. Have you tried and tested this script? @Jaykrishna1
