pdst.fm is classified as tracking content, unblocking allowed the podcast to load and play.

Verified, the issue is still reproducible with Strict ETP with the exceptions enabled:

• Privacy.trackingprotection.allow_list.baseline.enabled set to true
• Privacy.trackingprotection.allow_list.convenience.enabled set to true

Tested with Nightly 143.0a1 (2025-07-30) on Windows 10.

Sorry, I need to send a NI again. The exception for this bug wasn't properly deployed. So, request the verification again.

Verified, the issue is no longer reproducible with Strict ETP in Normal nor with Standard ETP in PBM with the exceptions enabled:

• Privacy.trackingprotection.allow_list.baseline.enabled set to true
• Privacy.trackingprotection.allow_list.convenience.enabled set to true
