Firefox tab groups: create one, save it and get it back

Updated 18 October 2026

Firefox has tab groups built in, with no add-on needed. Drag one tab onto another to make a group, right-click the group’s name and choose Save and close group to put it away, and reopen it later from the List all tabs menu at the right end of the tab strip.

Create a tab group

1. Drag a tab onto another tab, wait until the drop area highlights, and let go.
2. Or right-click a tab and choose Add Tab to New Group. Once you have groups, the item reads Add Tab to Group, with New Group inside. Ctrl+click several tabs first (Cmd+click on a Mac) to group them in one go.
3. Type a name and pick one of nine colors. You can change both later.

Click the group’s name to collapse or expand it. Hovering over a collapsed group lists its tabs, and dropping a tab on a collapsed group’s name adds it without opening the group. To take a tab out, right-click it and choose Remove from Group; a group with no tabs left is deleted.

What the group menu does

Right-click a group’s name to open Manage tab group, where you can also rename it and change its color:

Save a group and reopen it later

1. Right-click the group’s name and choose Save and close group.
2. To reopen it, click List all tabs at the right end of the tab strip (with vertical tabs, the List all tabs button on the toolbar). Recent tab groups lists your latest groups, open ones first, and Show all appears once you have more than five.
3. Click a closed group to open it in the current window, or right-click it for Open Group in New Window or Delete Group.

Typing a group’s name in the address bar also offers to open it. Save and close group is greyed out when the group holds only new tabs or blank pages, and it’s missing in private windows, whose groups are deleted when the window closes. Nightly builds of Firefox 160 (October 2026) rename List all tabs to Search and manage tabs, the name Mozilla’s help already mentions.

Do groups survive closing Firefox?

Yes. With Open previous windows and tabs ticked in Settings > Home and startup, they come back on the tab strip. With it off, Firefox keeps the groups from your last session in the List all tabs menu, and History > Restore previous session puts them back in place. Closing a window saves its groups to the same list.

Tab groups gone? Where to look

• Saved, in a window you closed, or from before a restart: List all tabs, under Recent tab groups or Show all. After a restart, History > Restore previous session also works (more on restoring a session).
• Deleted: click the menu button and choose History > Recently closed tabs. A deleted group appears under its own name, with Reopen tab group.
• From a private window: gone; Mozilla says those groups are deleted when the window closes.
• Grouped or ungrouped by surprise: Mozilla points to tab extensions. Turn them off one at a time in about:addons.
• Missing on another computer: groups don’t sync, so they were never there.

Do Firefox tab groups sync?

No. Mozilla says tab groups are local only and don’t sync with Firefox Sync, although with Sync on, the open tabs inside a group still appear under Tabs from other devices like any other tab. To take a group with you, save it as bookmarks, which do sync: choose Move group to new window, expand the group and press Ctrl+Shift+D (Cmd+Shift+D). Its copied links also work in our free URLs to bookmarks tool, which makes a file any browser imports.

Tab groups or containers?

They do different jobs and work together. A tab group arranges tabs in the tab strip. A container keeps a set of tabs’ cookies and sign-ins apart from the rest, so you can be signed in to two accounts on the same site. Containers are switched on with Use Container Tabs in Settings > Tabs and browsing.

On Android and iPhone

Firefox for Android has tab groups too. In the tab tray, touch and hold a tab and drag it onto another, or tap a tab’s three-dot menu and choose Add to group, then name the group and pick a color. Groups get their own section in the tab tray, Delete group removes one for good, and closing the last tab in a group makes Firefox ask whether to delete it. Mozilla’s current help for iPhone and iPad covers regular, private and synced tabs, with no tab groups.
