 you might be able to change some rules to be more restrictive.

 should be able to set the disable library validation entitlement[1] to
 false. Firefox needs to load libraries signed by Adobe and Google for
 Flash and Widevine video decoding respectively.

 WebExtensions using the native message API relied on helper applications
 that use Apple Events. I suspect Tor wouldn't need this and could set the
 entitlement to false.

 Thanks for those pointers. I've filed a bunch of tickets to harden our
 macOS Tor Browser. Your suggestions will be part of #32505.
