GmailRatio Legacy by RatioWorks helps keep Gmail usable on older Firefox systems while providing lightweight Gmail cleanup tools.

Features include Gmail compatibility mode, an optional Lite UI for slower computers, sender deduplication, a Gmail Cleanup panel, preview-before-unsubscribe, one-click Gmail-native unsubscribe, reviewed-sender bulk cleanup, and session-based unsubscribe history.

GmailRatio prioritizes Gmail's built-in unsubscribe controls and does not automatically visit arbitrary third-party unsubscribe links.

Privacy is designed for personal and business environments. GmailRatio does not transmit or remotely store email bodies, passwords, attachments, contacts, sender lists, browsing history, or analytics. Compatibility and Lite UI preferences may be stored locally in the user's Firefox profile. Temporary cleanup state remains local to the Gmail browser session.

GmailRatio is intended to improve compatibility and workflow on older Firefox installations. Compatibility mode cannot add browser-engine APIs that are physically missing from an older Firefox release.
