Why flagged

The source is a Firefox add-on (.xpi file) from Mozilla's official CDN, which is a legitimate and trusted host for Firefox extensions, despite not being on the analyzer's whitelist.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The source is a Firefox add-on (.xpi file) from Mozilla's official CDN, which is a legitimate and trusted host for Firefox extensions, despite not being on the analyzer's whitelist.

1 higher static finding superseded - not the current verdict (shown for transparency)

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
