1Password 7 Legacy Extension v4.7.5 – Manifest V3 Edition

Overview

This is an unofficial, community-maintained port of the original 1Password Legacy Extension v4.7.5, updated to support Manifest V3 for ongoing compatibility with modern Firefox browsers.



Important Notice

⚠️ This extension is NOT officially developed or supported by AgileBits (1Password).

• A community preservation project created to maintain the legacy desktop app integration.
• A valid 1Password license from AgileBits is still required.
• Requires the 1Password Desktop Application (v4.x or compatible standalone version).
• This extension simply allows continued use of software you already own.

Why This Extension?

When AgileBits discontinued support for the classic 1Password browser extension, many users were left relying on their standalone desktop vaults.
This port ensures that those users can continue using their existing software with:

• Future compatibility through Manifest V3 compliance
• Preserved functionality for standalone desktop licenses
• No cloud dependency — fully offline operation
