How do I reopen a closed window in Chrome?

Press Ctrl+Shift+T, or Cmd+Shift+T on a Mac. Chrome reopens the most recently closed tab or window. You can also open the Chrome menu, choose History and click the closed window under the recently closed list.

What if Chrome crashed and there is no Restore button?

Open History with Ctrl+H and look at the recently closed list, then search the full history by a word from the page title. History lists single pages, not which tabs were open together.

Chrome closed and lost my tabs: how to get them back

Press Ctrl+Shift+T (Cmd+Shift+T on a Mac) straight away. Chrome reopens the last tab or window you closed, and each further press goes one step further back. If Chrome crashed, open it again and look for a Restore button on the small message near the top right. Chrome's own tools cover most cases, and this guide goes through them in order.

What to try, in this order

Reopen the closed window. Press Ctrl+Shift+T. If you closed a whole window, the whole window comes back with its tabs. Press it again to go back one more step.
Look for the crash message. After a crash, Chrome can show a message that it did not shut down correctly, with a Restore button. Press it. It is easy to miss if you open Chrome and click away at once.
Open the Chrome menu, then History. The top of that list shows recently closed tabs and windows. A closed window appears as one line, for example "5 tabs". Click it to reopen all of them.
Search your history. Press Ctrl+H, or type chrome://history in the address bar. Pages are listed by day, with a search box above them. If you remember a word from the title or the site, search for it.
Check other devices. On the same history page, "Tabs from other devices" lists tabs open on your phone or another computer, if you are signed in to Chrome with sync turned on.

Two limits are worth knowing. History lists pages you visited. It does not remember which pages were open together, so a window of twelve tabs comes back as twelve separate lines. And private (Incognito) windows leave no history, so nothing can bring those back.

Stop it happening again

In Chrome, open Settings, then "On startup", and pick "Continue where you left off". Chrome then reopens the tabs from your last session every time it starts. Firefox has a similar choice in its settings, and its History menu has "Restore Previous Session". Microsoft Edge uses the same Ctrl+Shift+T key as Chrome.

This setting only helps when the browser closes in an ordinary way. If a profile is damaged, or you picked a different setting last week, there may be nothing to continue from. That is the gap an add-on can fill.

Where Tabsafe helps, and where it does not

Tabsafe saves a snapshot of your open windows, tabs and tab groups a few seconds after each change, and again every 15 minutes. It also logs each tab at the moment you close it. When the browser starts, the newest snapshot is kept as "Before restart", so the state of your last session stays in the list. From the side panel you can restore one tab, a group, a window or a whole snapshot, and pinned tabs and groups come back as they were.

The free plan keeps 14 days of snapshots and closed tabs. Pro keeps 365 days. New installs get 7 days of Pro, with no card. Pro costs €12 for a year or €29 once, as one-time passes that do not renew.

Some honest limits:

Tabsafe runs in Microsoft Edge and Firefox on desktop. It is not offered for Chrome, so in Chrome the steps above are what you have.
It can only restore what it saw. A crash that happened before you installed it cannot be undone.
Private windows are never recorded.
Pages such as about: and edge:// addresses cannot be opened by an extension, so they are skipped when you restore.
If you restore more than 100 tabs at once, Tabsafe asks you to confirm first.

If you use Edge or Firefox and a crash has cost you tabs before, a snapshot taken a few minutes earlier is the quickest way back. If you only use Chrome, set "Continue where you left off" and learn Ctrl+Shift+T.
