Only reasonable explanation I can come up with is that I installed it before this requirement was made and my install is grandfathered in

Without a nightly or dev version I’m running bypass paywalls clean from github, persistently on the latest Firefox desktop release. I do not believe it’s signed by Mozilla, but I could be wrong

On mobile that may be the case, but on desktop you can definitely install extensions not signed by Mozilla

Manifest v3 is about add-ons or extensions like ad blockers, grease monkey, etc. Manifest v3 gets rid of some features of Manifest v2 that will severely hamper ad blocking. Mozilla has committed to keeping manifest v2 support in addition to v3 as a bypass to this

SCUBA, LASER, JPEG, ROM, etc. all break the “pronounced as the nested word” argument.

I’m down for people to pronounce it however they please (assuming it’s recognizable as gif), but the post-hoc rationalizations trying to prove their side as the one true pronunciation are silly. The only rationalization that makes any sense to me is the “creator pronounces it as jif”, but language doesn’t work that way so even that doesn’t matter as far as “one true pronunciation” goes.
