@Vinod Survase, Thanks for posting in Q&A.
According to your description, I know that you cannot see “Managed by your organization” on Firefox browser.
Based on my testing, I deploy Firefox via Intune and sign-in an account, but it not show “Managed by your organization” on Firefox browser, and then I deploy a device custom configuration profile to Firefox and sign in with account, it shows success in Intune but still unable to see “Managed by your organization” on Firefox browser which the browser is applied to the custom policy.
Chrome and Edge with account can apply policy successfully and see “Managed by your organization”. It seems “Managed by your organization” is not supported on the Firefox.
Thanks for your kind understanding.
