tabGroups.TAB_GROUP_ID_NONE

The tab group ID value returned when a tab isn't in a tab group.

Its value is -1.

This value can appear as groupId in these API functions:

• tabs.group()
• tabs.ungroup()
• tabs.query()
• tabs.Tab

The tabGroups.TAB_GROUP_ID_NONE constant is part of the tabGroups namespace, which is only available when the tabGroups permission is granted. If your extension doesn't require the tabGroups permission, use -1 instead of tabGroups.TAB_GROUP_ID_NONE.
