Latest version
Version 1.2.0
Released Sep 24, 2026 - 180.62 KBWorks with firefox 140.0 and later1.2.0: Pinning a tab that is in a group is no longer undone when "Keep tabs in their groups" is on. Much faster with many tabs open: restoring or reopening a large window no longer makes the add-on do work proportional to every open tab. The one-minute integrity check now runs reliably even while the browser is busy, and the add-on recovers on its own if its startup ever fails. If a settings change cannot be saved, the popup no longer shows it as applied. Development tooling updated.Source code released under Tab Group Keeper Proprietary License
