"Turning Off Update Reminders in Firefox"

Try this.

https://github.com/mozilla/policy-templates#manualappupdateonly

ManualAppUpdateOnly Compatibility: Firefox 87 There is no policies.json file.

It is available for Fx 87 and subsequent versions. You have to create the file yourself using the code provided and place it in your distribution folder. See the file README. md at the top of the page.

EDIT : https://support.mozilla.org/en-US/kb/customizing-firefox-using-group-policy-windows

followed the instructions: 1. Created policies.json from text file, 2. copy/pasted the script {

 "policies": {
   "ManualAppUpdateOnly": true | false
 }

} 3.Copied policies.json in c:\Program Files\Mozilla Firefox\

Did I something wrongly? It didn't work.

According to the readme file, you have to create a directory called distribution and place the file there. I think you would need to reboot your computer.

Created the folder and placed the file there. c:\Program Files\Mozilla Firefox\ distribution

No luck. The notification keeps working.
