`1.0.<minutes since 2020>` -> `YYYY.M.D.HHMM` UTC, from the commit time of
the newest change to a packaged extension file. Same clock and same commit as
before; readable instead of opaque, and the same value the rest of the family
derives.
The hold on this step was two questions about AMO, and Mozilla's own docs
answer both:
^(0|[1-9][0-9]{0,8})([.](0|[1-9][0-9]{0,8})){0,3}$
1. four all-numeric segments -> ACCEPTED ({0,3} more after the first).
2. leading zeros -> REJECTED. A segment is the single digit
`0` or starts 1-9, so `08` and `0201` are refused. MDN says it in prose
too: "Non-zero numbers must not include a leading zero."
So the documented fallback applies, extension only: the same numbers rendered
without the family's zero-padding. `2026.08.29.0201` and `2026.8.29.201` are
one value in two renderings — rule 148 defines comparison as numeric per
segment, under which they are equal — so nothing already published is
reordered, and left-padding each segment recovers the family string exactly.
HHMM stays one segment because AMO allows at most four.
The transition is safe in the other direction too: 2026 > 1, so every CalVer
outranks every published 1.0.x. build.yml's downgrade guard confirms it.
Also in scope:
* MAJOR.MINOR is gone. `cmd_major_minor`, `cmd_patch` and VERSION_EPOCH go
with it, the committed version in manifest.json / package.json is now
wholly inert, and ci.yml's MAJOR.MINOR-agreement check is retired rather
than left running beside a fact that stopped existing (rule 22).
* ci.yml's `extension-version` lane now asserts Mozilla's regex verbatim
instead of a loose `^[0-9]+(\.[0-9]+)*$` — which would have passed the
padded shape. It also asserts YYYY.M.D.HHMM, because AMO would accept a
regression to `1.0.<minutes>` while that orders below everything signed
since. Checking here is the point: AMO 409s on re-signing, so a version it
rejects is burned and cannot be reused.
* `artifacts.sh version extension` delegates to packaging.sh, so the two
cannot answer differently. The direction matches the existing one —
artifacts.sh already asks packaging.sh for the extension's path set.
#3156 is what makes this commit safe to make: packaging.sh is in web's path
set, so the web revision moves with the extension version and build-web
rebuilds instead of republishing an image bundling the previous XPI.
Scribe #3138.

FabledCurator Firefox Extension
Self-hosted Firefox extension that pushes session cookies from supported platforms (Patreon, SubscribeStar, Hentai-Foundry, Discord, Pixiv) into FabledCurator, and lets you add a creator as a Source from their page in one click.
Install (operator)
The signed XPI is bundled into the FC Docker image — :dev and
:latest each carry their own channel's build. Open FC →
Settings → Maintenance → Browser extension → click "Install Firefox
extension". Firefox shows its native install prompt. After installing,
open the extension's options page (about:addons → FabledCurator →
Preferences) and paste in the FC URL + extension API key shown on the
same card.
Develop
cd extension/
npm install --no-save # web-ext only
npm run lint # web-ext lint
npm run test:unit # vitest — lib/ logic + packaging/version checks

Versioning — the committed number decides nothing
The shipped version is derived, not committed. scripts/packaging.sh version returns YYYY.M.D.HHMM in UTC: the commit time of the newest change
to a packaged extension file. build.yml computes it and stamps it into both
manifest.json and package.json at build time. The stamp is never
committed — the commit carrying it would itself be a change to the extension,
which would move the version again.
So:
- Editing the version does nothing. All of it is overwritten before web-ext ever reads it. There is no bump to make, and none to forget. There is no hand-set part left either: MAJOR.MINOR went away with milestone 318 step 8.
npm run buildlocally produces an XPI labelled with the committed version, since nothing stamped it. Fine for loading into a test profile; not what ships.
Why the extension is the one artifact that does not zero-pad. Every other
FC artifact emits rule 148's YYYY.MM.DD.HHMM. AMO will not take it: Mozilla's
grammar for addons.mozilla.org is
^(0|[1-9][0-9]{0,8})([.](0|[1-9][0-9]{0,8})){0,3}$
— each segment is the single digit 0 or starts 1-9, so 08 and 0201 are
rejected, and at most four segments are allowed. The extension therefore emits
the same numbers unpadded: 2026.8.29.201 where the rest of the family
says 2026.08.29.0201. Rule 148 already defines comparison as numeric per
segment, under which the two are equal, so nothing is reordered by the choice
and left-padding each segment recovers the family string exactly. ci.yml's
extension-version lane checks the derived string against that regex on every
push — the cheap place to find out, because AMO 409s on re-signing and a
rejected version is burned for good.
Why commit time and not a commit count: a count is per-branch, so dev and
main count different histories of the same code and their versions end up
ordered by which branch accumulated more commits rather than by which is newer.
Commit time gives both branches the same number for the same source — which is
exactly what lets one AMO signature serve both channels (family rule 149, FC
issue #3092).
Channels
dev and main each build and sign their own extension, and an install is
tied to whichever FC instance it points at — Firefox's static update_url
cannot apply here, since every FC install is a different host, so the extension
asks its configured backend. The channel therefore IS the instance.
Switching channel means repointing the FC URL in options and reinstalling from
that host; there is no separate channel setting, and adding one would
contradict each server build shipping its own extension.
The channel is reported beside the version, never inside it:
/api/extension/manifest answers {"version": "...", "channel": "dev"}. It is
optional — an instance that declares none simply omits the key, and the popup,
the toolbar tooltip and the Settings card all read exactly as they did before
the field existed. Do not be tempted to make it a -dev version suffix: the
comparator parses each dotted segment with parseInt, so a suffixed segment
reads as 0 and every dev build compares equal to every other, collapsing "no
update available" and "I cannot read this version" into one answer.
Release
Nothing to do by hand. Push to dev: build.yml signs the extension if this
change moved the version, caches the signed XPI as a Forgejo ext-<version>
release, and bundles it into fabledcurator:dev. Merging to main derives the
same version, hits that cache, and bundles the byte-identical XPI into
:latest with no second AMO call.
AMO refuses to re-sign a version it has already issued, so signing is one-shot per version — which is why the cache exists and why the version must never move backwards.
