Save the window, and name it
Save all tabs in the Latr popup stores every tab in the window with its groups. Give it a name and it is kept for good. Close the window if you want the memory back.
A tab group lasts exactly as long as its window. Latr keeps a copy you can name, look inside and restore - as a window, with every group back under its own name and colour.
The problem
You spend an afternoon sorting forty tabs into Research, Tickets and Reading. Chrome can save a group if you remember to right-click and say so - and the window you lose is the one you did not. A crash, an update or a stray click on the wrong X, and the unsaved groups are gone, or back as a pile in a window you were using for something else.
How it works
Save all tabs in the Latr popup stores every tab in the window with its groups. Give it a name and it is kept for good. Close the window if you want the memory back.
It comes back as one window, not as forty tabs dropped into the one you are in - each group under its name and colour, folded if it was folded. Or open it in place of the window you are in.
Autosave keeps the newest ten versions of a window as you work - up to fifty if you like - and Latr can save a window the moment you close it. A window you named, archived or brought back sits on its own list and is never rotated away. Watch it happen.
Only in Latr
From a group's menu in Open tabs, Remind me closes the group and brings it back, as a group, at the time you pick - tomorrow morning, Monday, after the meeting. Keep in a folder files every page in it in your library instead, and a library folder opens back up as a tab group.
Questions
Open the saved window and choose Open every tab. It comes back as a new window with each group rebuilt - name, colour and whether it was collapsed. If you turned on save on close, windows are saved as they close, so there is something to restore even when you forgot.
Chrome does, and it is worth knowing about: right-click the group label, choose Save group, and it becomes a coloured pill on the bookmarks bar that reopens the whole group later. It will also sync between signed-in devices, though plenty of people report that part being unreliable. What it does not do is save a whole window of several groups as one thing, keep a copy you own as a file rather than in a Google account, or give the group a time. It also only covers the groups you remembered to save - and the window you lose is almost always one you had not.
Yes. A saved window stores which tabs belonged together, what each group was called and its colour, and a folded group comes back folded. Only groups that still hold a page are stored - a group whose every tab was a browser settings page would come back as an empty label, so it is left out.
Putting groups back uses the browser’s tab-groups permission, which Latr does not ask for at install. The first time you restore a window that had groups, it asks once. Decline, and the window still comes back - just without its groups.
In your browser’s own extension storage, on your machine. There is no account and no server. Saved windows do not travel over sync - they are larger than a synced item may be - and they are not part of a backup file either. To move one to another machine, share it as one link and add it there as a window - its group names and colours stay behind.
Yes. Edge and Chrome share the same tab groups. Firefox has had tab groups since 2025, and Latr restores them there too.
Free, no account, and nothing leaves your device. About ten seconds to install, and one keystroke to use.
