Forty tabs open, and you want the window gone without losing what is in it. Three native options, in the order you should reach for them.

Bookmark all tabs — Ctrl+Shift+D

Ctrl+Shift+D (Cmd+Shift+D on a Mac), or right-click any tab and choose Bookmark all tabs. Chrome asks for a folder name and writes every open tab into it.

Give the folder a name with the date in it — 2026-10-09 research beats New folder (3), and you will be reading it in three weeks. To get the whole set back, right-click the folder in the bookmarks bar and choose Open all.

This is the one to use if you only learn one. It works in Chrome, Edge and Firefox, the result is a real file you can export, and nothing depends on the browser being in a good mood next time it starts.

What it loses: the grouping, the ordering, your scroll position in each page, and any sense of which of the forty actually mattered.

Reopen on startup

Settings → On startup → Continue where you left off (Firefox: Open previous windows and tabs). Close the browser, open it tomorrow, everything is back.

Useful, and not a save. It protects the last session only — open the browser, close two windows by accident, and the thing it will restore tomorrow is that mistake. It also means you never start with a clean browser, which for some people is the problem rather than the fix.

Recently closed

History → Recently closed lists closed windows as single entries, so a whole window comes back in one click. Ctrl+Shift+T walks backwards through them.

Excellent for the last ten minutes. It holds a limited number of entries, it is per session, and clearing browsing data clears it — so treat it as an undo, never as storage. We wrote about restoring closed tabs separately.

The gap all three leave

Every method above answers where did my tabs go. None of them answers when am I going to deal with these.

That is the actual problem with the forty tabs. They are open because each one is something you have not finished — an article, a ticket, a thing to book — and a bookmark folder called 2026-10-09 research is the same forty unfinished things in a place you will never deliberately visit. The tabs at least nagged you. The folder does not.

This is why a bookmark folder full of good intentions feels like a graveyard within a month. You did not lose the links. You lost the reason you had them open.

Saving them with the reason

Latr saves the window the way the bookmark folder does — every tab, plus the tab groups, their names and colours, restored as a window rather than as a pile — and then adds the part the browser has no concept of: a time.

  • Save the window and close it. It is on the saved-windows page, named, with its groups intact, until you delete it.
  • Give any page in it a time and it stops being a saved link. The page reopens on its own at the moment you chose — Monday at nine, after the meeting, in three hours — at the line you had scrolled to rather than the top.
  • Keep this tab, stash the rest is one command: the thing you are reading stays, the other thirty are saved and closed as one batch you can undo in one press.
  • And it saves a window when you close one, without being asked, so the window you lose is already saved.

No account, nothing sent anywhere, and the install dialog carries no permission warnings.

The short version

Use Ctrl+Shift+D before you close anything important — it takes two seconds and it is a real file. Turn on Continue where you left off so an accidental quit costs nothing. And if the forty tabs keep coming back because none of them is finished, the thing to save is not the list, it is the list plus when you are going to look at it.
