Group names, domains, and packs
Rename canonical group labels, assign extra domains, hide groups, and import a signed community pack from a local file.
Switch to DeutschCanonical groups come from automatic grouping. Taxonomy edits change how those groups are labeled and which extra domains they claim. Custom groups are a separate destination you create yourself — see Create and manage custom groups.

Display names
Each canonical group header can show a display name that differs from the internal group key.
- Open the Groups view.
- Open Group actions on the group header.
- Choose Rename display name.
- Enter the label you want in the list and save.
The display name changes the label in Tab Organizer. It does not rename native Chrome Tab Groups by itself. Native titles follow Mirror or Tab Groups Sync (BETA) when those modes are active.
Extra domains
Use Assign domain when a site should join a canonical group that automatic grouping does not already choose.
- Open Group actions on the target group.
- Choose Assign domain.
- Enter the domain you want this group to claim.
- Refresh the list and confirm matching tabs appear under that group.
An extra domain is a taxonomy override, not a full Tab Rule. For URL, title, regex, or wildcard matching, use Tab Rules.
Hide a group
Hide group removes a canonical group from the popup list. Tabs that belonged to it regroup on refresh.
- Open Group actions on the group.
- Choose Hide group.
- Read Hide group? and confirm only if you want that category removed from the list.
- If you hid the wrong group, choose Undo while it is still offered.
Community packs
A community pack is a local .topack.json file with rules and taxonomy. Import runs offline: the extension reads the file you choose and does not fetch packs from the website.
- Open settings and find Community Pack.
- Choose Import community pack… and select a
.topack.jsonfile you already have. - Wait until validation finishes.
- If Resolve import conflicts appears, choose Keep mine or Take pack for every conflict.
- Apply the import only after every conflict has a choice.
Do not treat a pack file as a session backup. Packs change grouping configuration; they do not restore open tabs. For a recoverable product backup, use Export backup (JSON).
