Latest version
Version 3.13.0
Released Aug 1, 2026 - 378.56 KBWorks with firefox 142.0 and later- "Move tab to its group's window", from the right-click menu or an (unassigned)
keyboard shortcut. Sends a tab to the window where its group already lives,
for people who keep windows roughly by topic. Grouping still never moves tabs
between windows on its own ([#90], closes [#68]).

Version 3.12.0
Released Jul 31, 2026 - 377.44 KBWorks with firefox 142.0 and later- Optional "wait until I view a new tab before grouping it". Off by default.
When on, a tab opened in the background from another tab stays next to the
tab it came from until you switch to it, instead of being filed away before
you have seen it. Foreground tabs, tabs with no opener, and the "Group Tabs"
button are unaffected ([#89], addresses [#68] / [#88]).

- Optional "wait until I view a new tab before grouping it". Off by default.
Version 3.11.0
Released Jul 31, 2026 - 376.02 KBWorks with firefox 142.0 and later- Rules can match query strings. A pattern containing
?is matched against
the query as well as the host and path, so tabs on one domain can be split by
a parameter —domain.cz/?ticket={ticket}puts each ticket in its own group,
and a regex capture does the same. Patterns written before this behave
exactly as they did ([#87], closes [#27]).
- Keyboard shortcuts for turning auto-grouping on or off, grouping all tabs,
ungrouping all tabs, and collapsing or expanding every group. No keys are
assigned by default — installing takes none of your existing shortcuts, and
nothing fires until you assign keys in the browser's own shortcut settings.
Advanced → Keyboard shortcuts opens that page ([#86], closes [#25]).
