TabRatio od RatioWorks

TabRatio is a local-first Firefox tab and workspace organizer built to make large browsing sessions easier to manage.

Features include smart groups for common sites, open-tab search, duplicate-tab detection and cleanup, Tab Parking for stale tabs, saved workspaces, protection for pinned and audio-playing tabs, configurable stale-tab thresholds, a first-run setup page, and a full dashboard.

TabRatio does not collect, sell, share, or transmit browsing data. Smart grouping and tab management run locally in Firefox. Settings, parked tabs, and saved workspaces are stored in Firefox extension storage on the user's device. No analytics or advertising SDKs are included.
