Problem: Even after fixing the hls.js file naming (was 'hls.min.js', now
'hls.js'), videos don't play in the viewer. Likely root cause is CORS
blocking chrome-extension:// requests to phncdn.com CDN URLs that lack
CORS headers for extension origins.
Solution — two-layer fix:
1. Service worker proxy (background.js):
- New GOON_PROXY_FETCH handler fetches any URL via native fetch()
(no CORS restrictions in the service worker)
- Returns base64-encoded response data to the viewer
2. Custom HLS loader (viewer/viewer.js):
- HlsLoader implements hls.js Loader interface
- For phncdn.com/pornhubcdn URLs: proxies via GOON_PROXY_FETCH
- For all other URLs: uses native XHR (bypasses proxy overhead)
- Config passed to hls.js only when manifest URL needs proxying
3. Diagnostics (viewer/viewer.js):
- CORS check at page load for phncdn.com and per-video URL
- Full storage dump of video entries in console
- Manifest URL logging on each HLS load attempt
- Proxy activation logging for debugging
