Google Account Switcher by Peter

If you use multiple Google accounts, you know the pain of constantly being signed into the wrong one. Google Account Switcher fixes this by automatically adding the correct authuser parameter to Google URLs, so you always land on the right account.

Features:

• One-click account import — Pull your signed-in Google accounts directly from your browser session.
• Default account — Set a global default that applies across all Google services.
• Per-service overrides — Use your work account for Gmail and Cloud Console, your personal account for YouTube and Photos, or any combination you need.
• Global on/off toggle — Quickly disable redirects without losing your configuration.
• Lightweight — No external requests, no tracking, no background overhead. All settings are stored locally.

Supported services: Gmail, Google Drive, Docs, Sheets, Slides, Calendar, Meet, Chat, Cloud Console, Maps, Photos, Contacts, Keep, Groups, and more.

How it works: When you navigate to a Google service without an account already specified in the URL, the extension injects the authuser parameter for your preferred account. If you've manually switched accounts or the URL already specifies one, the extension stays out of the way.

Privacy: This extension stores your configuration locally and makes no external network requests. Your account information never leaves your browser.
