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.
