Symptom (operator-flagged): the extension injected the Add-as-source button on a Patreon creator you had NOT subscribed to, but it disappeared once you were subscribed — the opposite of when it's useful. Root cause (extension logic, not Patreon security): Patreon serves a creator under three URL shapes — bare patreon.com/Atole, patreon.com/c/Atole, and patreon.com/cw/Atole (the 'creator workspace' URL you land on once subscribed; documented in patreon_resolver._VANITY_RE). The button's artist-page gate (PLATFORM_ARTIST_PATTERNS.patreon in platforms.js) and its byte-mirror probe pattern (_PLATFORM_PATTERNS in extension_service._derive) only matched the bare single-segment form and explicitly excluded c/. So the subscribed-view URL failed the gate → no button. The ingestion resolver already handled all three; only these two gates were too narrow. Fix: both regexes now accept optional cw/ and c/ prefixes and drop the strict single-segment end-anchor, so a creator's inner page (/cw/Atole/posts, /Atole/membership) also matches — robust to whatever exact shape the subscribed view uses. Nav-page exclusions (home/search/messages/notifications/library/ settings/posts + post permalinks) preserved. New unit test covers all three prefixes, sub-paths, and nav-page rejection (both regexes validated identically). Bump extension 1.0.7→1.0.8 so a fresh signed XPI ships the fix (also exercises batch-5 web-ext-10's AMO sign path end-to-end on the main build).

FabledCurator Firefox Extension
Self-hosted Firefox extension that pushes session cookies from supported platforms (Patreon, SubscribeStar, Hentai-Foundry, Discord, Pixiv, DeviantArt) 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. 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 start # launches Firefox with extension loaded
npm run build # unsigned XPI in web-ext-artifacts/
Smoke checklist (after every release that touches extension/**)
npm run lintpassesnpm run startloads the extension in a clean Firefox profile- Options page accepts FC URL + key, indicator turns green
- Cookie export: log into patreon.com, click Patreon card → "X cookies exported"
- Discord token: open discord.com, click Discord card → "Token captured"
- Pixiv OAuth: click Pixiv card → login redirects, token stored
- Add as source: visit patreon.com/, click floating button → toast
- Subscriptions list: popup → "Sources" tab → list renders
- Check now: click play icon on source row → no error toast
Release
Bump manifest.json + package.json SemVer (both files) and commit
under extension/**. The .forgejo/workflows/extension.yml workflow
runs web-ext sign on main, commits the signed XPI to
frontend/public/extension/, and the next FC server build bundles it
into the Docker image.
