Arc Exporter (macOS)

Export Arc Browser profiles into cross‑browser importable artifacts, with optional direct import into Chrome/Chromium. Also includes optional helpers for Firefox/Zen.

Features

• Exports per‑profile, cross‑browser artifacts under arc-export/:
  • bookmarks HTML (NETSCAPE format; importable by most browsers)
  • passwords CSV (widely importable)
  • cards CSV (reference only)
• Copies Arc profiles into new Chrome/Chromium profiles (non‑destructive), including:
  • passwords/cards merged into the Chrome profile (re‑encrypted with Chrome key)
  • extensions install is EXPERIMENTAL and disabled by default (see below)

Requirements

• macOS
• Python 3.9+
• Arc and Google Chrome installed
• OpenSSL CLI available (for Chromium v10 decryption)

Quick start

1. Fully quit Chrome and Arc (Cmd+Q).
2. Run:

python3 main.py

This writes portable exports to arc-export/ and, by default, also creates new Chrome profiles (e.g., Profile 1, Profile 2, …). Use the flags below to tailor behavior.

Common flags

# Only copy profiles + extensions into Chrome (skip exports)
python3 main.py --no-passwords --no-cards --no-bookmarks

# Only export artifacts (no Chrome profiles)
python3 main.py --no-copy-profiles

# Experimental: build AMO mapping + policies.json per profile (Firefox/Zen)
python3 main.py --experimental-amo-mapping

# Experimental: export cookies.sqlite per profile (Firefox/Zen)
python3 main.py --import-cookies

# Experimental: attempt per‑profile Chrome extension install (UNSTABLE)
python3 main.py --experimental-extensions

Outputs

• Cross‑browser exports: arc-export/profiles/<ArcProfileName>/
  • bookmarks_<ts>.html (NETSCAPE)
  • passwords_<ts>.csv
  • cards_<ts>.csv
  • optional extensions_report_<ts>.json and policies_<ts>.json (Firefox/Zen)
  • optional cookies_<ts>.sqlite (Firefox/Zen)
• Chrome/Chromium (optional): ~/Library/Application Support/Google/Chrome/Profile N

Scope and formats

• By default, exports are generic/portable and not Firefox‑specific.
• Firefox/Zen‑specific artifacts are only created when you use the optional flags:
  • --import-cookies → produces Firefox‑format cookies.sqlite
  • --experimental-amo-mapping → suggests Firefox/Zen policies.json
  • No direct extension install to Firefox/Zen is performed.

Experimental features (status: currently broken)

• --experimental-extensions: Per‑profile extension preinstall for Chrome. Due to Chrome integrity checks and policy scope, automated installs may not complete or may require manual confirmation in each profile.
• --experimental-amo-mapping: Tries to map Chrome extensions to AMO and write suggested policies.
• --import-cookies: Exports Arc cookies into a Firefox‑format database.
