+This policy was updated in Firefox 78 to allow enabling ciphers as well. Setting the value to true disables the cipher, setting the value to false enables the cipher. Previously setting the value to true or false disabled the cipher.

+### DisableDefaultBrowserAgent
+Prevent the default browser agent from taking any actions. Only applicable to Windows; other platforms don’t have the agent.
+
+The browser agent is a Windows-only scheduled task which runs in the background to collect and submit data about the browser that the user has set as their OS default. More information is available [here](https://firefox-source-docs.mozilla.org/toolkit/mozapps/defaultagent/default-browser-agent/index.html).
