The extension is installed per-instance from the operator's FC host, so Firefox's
static update_url can't apply (each instance has a different host) and updates
were fully manual. Add a self-hosted-friendly update surface that reuses the
existing public GET /api/extension/manifest ({version, latest_url, sha256}):
- lib/api.js: getExtensionManifest().
- background.js: checkForUpdateInfo() compares the instance's latest published
version against runtime.getManifest().version (dotted-numeric compare so
1.0.10 > 1.0.9); CHECK_UPDATE message handler; refreshUpdateBadge() sets a
toolbar badge via browser.action; a daily browser.alarms check plus on
startup/installed. New 'alarms' permission (non-prompting).
- popup: an 'Update available — vX' banner with an Update button that opens the
signed XPI (web root, /api stripped like OPEN_ARTIST_PAGE) → Firefox's native
install prompt. Never blocks the popup on a failed check.
No backend changes (endpoint already exists). Bump 1.0.8→1.0.9 so this ships;
from here on updates surface themselves instead of needing a manual reinstall.
