Like I mentioned earlier, we’re still monitoring Chrome’s manifest v3 proposals. Their recent post indicates that they are still iterating on some of the ideas they would like to implement, including changes that would impact content-blockers.
Regardless of what happens with Chrome’s manifest v3 proposals, we want to ensure that ad-blockers and other similarly powerful extensions that contribute to user safety and privacy remain part of Mozilla’s add-ons ecosystem while also making sure that users are not being exposed to extreme risks via malicious use of powerful APIs.
