# Bonfire — Chromium login stays on homepage (2026-08-17)

Site: **https://bonfire.hacktivism.ch/**  
Canonical: `configs/bonfire/README.md` (section *Login in Chromium*).

## Symptom

- **Firefox:** Log in and `/login` work.
- **curl** `https://bonfire.hacktivism.ch/login`: 200, title *Log in*.
- **Chromium** (operator profile, tab on `/`): **Log in** click does nothing; typing `/login` in the address bar still shows *Explore local activities*. Incognito/Firefox not affected.

Not the `isoc` account (email + username profile exist; login API ok).

## Checks

| Check | Result |
|-------|--------|
| Guest `/` HTML | `data-live-socket="false"`; **Log in** is `<a href="/login" data-phx-link="redirect">` |
| `#modal` | `opacity-0 modal-closed`; `modal_invisible` loading stub has **no CSS rule** (Chromium can show a black overlay) |
| Bonfire JS | `navigator.serviceWorker.register("/pwabuilder-sw.js", {scope: "/"})` |
| `/pwabuilder-sw.js` (before kill-switch) | 404; hashed `pwabuilder-sw-*.js` exists under `priv/static/` |
| UI | badge **Federation disabled** while container `FEDERATE=true` |

## Workaround

Unregister the worker for `bonfire.hacktivism.ch` in that Chromium profile (`chrome://serviceworker-internals` or DevTools Application), clear site data, hard reload. Then `/login` matches Firefox.

Host copies (optional, recreate-volatile in the image): `~/koopa-bonfire/data/branding/{pwabuilder-sw.js,hacktivism-login-fix.css,unregister-sw.js}`.

## Upstream

Not marked known in Bonfire GitHub (2026-08-17): no issue matches `pwabuilder-sw` or “service worker login”. Related PWA issues are push (#1292) and widgets (#1758), not Chromium `/login` hijack.

**Still open locally.** File a bonfire-app issue when ready: `configs/bonfire/TODO-chromium-login-upstream.md`.
