Is Letterboxd Streaming Providers safe?

Low risk

Letterboxd Streaming Providers bundles a decodable TMDB API bearer token and sends it to api.themoviedb.org.

The extension stores an obfuscated TMDB bearer token in its bundled settings file, decodes it at startup, and uses it as an Authorization header for TMDB API requests. Those requests search film titles and check streaming-provider availability so the extension can filter Letterboxd pages.
