Tabique by Mu88

Tabique organizes your current window in seconds. See your tabs clustered by site or title, then act on whole groups at once. Pin or unpin clusters, move selected groups to the start or end of the strip, and close the ones you no longer need. A Unique Sweep closes duplicates and reorders everything so related tabs sit together. You choose the grouping method and duplicate detection in Options. Tabique never touches page content—no content scripts—so it stays fast and private.

Under the hood, Tabique keeps permissions lean. It uses tabs to list, sort, move, pin, mute, and close tabs in the current window, and storage to remember your preferences. There are no inline scripts, no unsafe innerHTML, no remote resources, and no analytics. All code is bundled and self-hosted to comply with AMO policies. A keyboard shortcut (Alt+Shift+U) runs Unique Sweep.
