Group new tabs automatically in Waterfox

Waterfox can place a newly opened tab into the same tab group as the tab that opened it. Automatic tab grouping is off by default and only extends an existing tab group. It does not create, name or classify groups for you.

Turn on automatic tab grouping

1. Click the Waterfox menu button and select Settings.
2. Select Tabs and browsing.
3. Find Waterfox tabs, then open Automatic tab grouping.
4. Turn on Group new tabs with the tab that opened them.
5. Under Where new tabs join the group, choose the placement you want.

The placement control is unavailable while automatic grouping is off. Waterfox saves both settings automatically.

Choose where the new tab goes

• After the tab that opened them places each new tab directly after its source tab. This is the default.
• At the start of the group places it before the group’s other tabs.
• At the end of the group appends it after the group’s other tabs.

Use automatic grouping

1. Create or open a tab group.
2. Select a tab inside that group.
3. Open a link or another new tab from it.

Waterfox adds the new tab to that existing group and moves it to the selected placement. If the source tab is not grouped, the new tab stays ungrouped.

Practical caveats

• Automatic tab grouping controls regular tab groups, not parent and child branches from Waterfox tree tabs.
• Waterfox leaves tabs that already have a group assignment alone, including tabs restored with a session or reopened through undo.
• Waterfox does not pull a new tab into a group while that group is collapsed. The first tab opened after the collapse is also left ungrouped so opening the group does not unexpectedly move a tab into it.
