Tom, do we need anything other than https://phabricator.services.mozilla.com/D141418 for this bug? Thanks!

Yes, we will need to flip fission.omitBlocklistedPrefsInSubprocesses to true-by-default for all branches to enable the actual protection.

We'll also want to enable fission.enforceBlocklistedPrefsInSubprocesses in Nightly/Early Beta at least (ideally all channels) but before we do that we need to keep it opt-in for now while we iterate on Bug 1766866.
