Hi All, How can be the Enhanced Tracking Protection set to Strict via group policy. Thank you

Or via policies.json ?

You can use the Preferences policy to set

browser.contentblocking.category

to "strict"

We're looking into making this easier to set via policy

More info. Strict is setting that value as well as a combination of prefs.

   network.cookie.cookieBehavior = 5

Must be set explicitly via the Preferences policy

   privacy.trackingprotection.fingerprinting.enabled = true

Set if EnableTrackingProtection->Fingerprinting is true

   privacy.trackingprotection.cryptomining.enabled = true

Set if EnableTrackingProtection->Cryptomining is true

   privacy.trackingprotection.socialtracking.enabled = true

Must be set via the Preferences policy

   privacy.trackingprotection.enabled = true
   privacy.trackingprotection.pbmode.enabled = true

Set if EnableTrackingProtection->Enabled is true

Again, I'm looking into making this simpler.
