Is Video Downloader Pro safe?

Low risk

Video Downloader Pro embeds a hardcoded Twitter API credential that any user of the extension can extract.

The extension bundles a Base64-encoded Twitter consumer key and consumer secret in its source code to enable Twitter video downloads. On each Twitter video request, it sends this credential to api.twitter.com to obtain a Bearer token for app-only API access. Because the credential ships verbatim in the extension package, it is trivially readable by anyone who inspects the bundle.
