All extensions disabled due to expiration of intermediate signing cert

Update: We have rolled out a partial fix for this issue. We generated a new intermediate certificate with the same name/key but an updated validity window and pushed it out to users via Normandy (this should be most users). Users who have Normandy on should see their add-ons start working over the next few hours. We are continuing to work on packaging up the new certificate for users who have Normandy disabled.

I've been through all of Firefox `about:config` a few times in the past, fixing preferences to, e.g., try to disable umpteen different services that leak info or create potential vulnerabilities gratuitously, but this is the first I recall hearing of Normandy.

Apparently I missed `app.normandy.enabled`, because I think I would've remembered a name with connotations of a bloody massive surprise attack.

Incidentally, `app.normandy.enabled` defaults to `true` in the `firefox-esr` Debian Stable package. Which seems wrong for an ESR.

For personal use (not development), I run 3 browsers (for features/configurations and an extra bit of compartmentalization): Tor Browser for most things, Firefox ESR with privacy tweaks for the small number of things that require login, and Chromium without much privacy tweaks for the rare occasion that a crucial site refuses to work with my TB or FF setup.

Today's crucial cert administration oops, plus learning of yet another very questionable remote capability/vector, plus the questionable preferences-changing being enabled even for ESR... is making me even less comfortable with the Web browser standards "big moat" barrier to entry situation.

I know Mozilla has some very forthright people, but I'd really like to see a conspicuous and pervasive focus on privacy&security, throughout the organization, which, at this point, would shake up a lot of things. Then, with the high ground established unambiguously, I'd like to see actively reversing some of the past surveillance&brochure tendencies in some standards. And also see some more creative approaches to what a browser can be, despite a hostile and exploitive environment. Or maybe Brave turns out to be a better vehicle for that, but I still want to believe in Mozilla.
