Inspect pasted links, text files and DLC containers before queue insertion and resolve supported hoster metadata without starting downloads. Group multipart files into expandable packages with size, status, availability, timestamps, filtering and stable selection. Add selected or complete transfer to Downloads while retaining entries on failed or partial handoff. Keep collector toolbar spacing consistent and show the full 1Fichier identity with its provider icon in Downloads.
Add centralized browser security helpers for restrictive BrowserWindow profiles, navigation denial, popup denial, permission denial, and exact HTTPS host allowlists. Apply those policies to the main renderer window and to the Real-Debrid and AllDebrid browser-login windows without weakening the credential renderer boundary.
Add shared IPC sender validation for renderer handlers so development accepts only the local Vite origin and non-development accepts only the built file renderer tree. Route the registered renderer IPC handlers through the shared guard and restrict app:open-external to the same exact HTTPS allowlist.
Cover the hardening with focused red-green tests for untrusted navigation, popup handling, permission requests, exact host/subdomain matching, packaged file renderer boundaries, untrusted IPC senders, and both browser-login window profiles.
