Rewind and closed tabs
Rewind keeps the tabs and windows you close so you can bring them back, on this computer only. You can undo a close right away, reopen the last tab with a key, or open the Rewind page to search everything you closed in the last few days.
Get a tab back
| Situation | What to do |
|---|---|
| You closed a tab seconds ago | Choose Undo in the message Tab closed. If you closed several tabs together, one Undo brings back all of them (3 tabs closed). Closing a group says Group "{name}" closed. |
| You closed a tab a moment ago | Press Ctrl+Shift+T (Reopen closed tab). It brings back one tab, the newest one you closed, in its old place, group and split. |
| You closed a window | Choose Undo in Window closed or Window with N tabs closed, which appears in another window of the same profile. Or open Rewind and use the Windows view. |
| You closed something a while ago | Open Rewind with Ctrl+Shift+H. |
On a Mac, press Cmd+Shift+T to reopen a tab. Cmd+Shift+H does not open Rewind on a Mac. Open Rewind from the Acira menu or command search, or record a key for it in Settings › Shortcuts.
Recently closed
Open the Acira menu and choose Recently closed. It lists the last six tabs you closed, with their sites and how long ago. Choose one to bring it back in the background, in its old group. The last row, Open Rewind, opens the full page. If nothing was closed, it says Nothing closed lately.
Open Rewind
- Press Ctrl+Shift+H (Windows).
- Or open the Acira menu and choose Rewind.
- Or open command search and choose Open Rewind.
The page opens with the search box ready. It has two views, chosen at the top: Tabs and Windows. Acira remembers the view you used last.
Tabs view
The Tabs view is a flat list of closed tabs, newest first, in bands: Last hour, Earlier today, Yesterday, This week and Older. Each row shows the page's icon, title, site and when you closed it. A row can also show the tab group the tab was in and the tab it was split with. Type in the search box to match titles, addresses, sites and group names.
| Action | How |
|---|---|
| Bring the tab back | Click the row, or press Enter. The tab opens in the background in its old group. It never replaces a tab that is open. |
| Bring it back in a new window | Press Ctrl+Enter (Cmd+Enter on a Mac), or choose the new-window button on the row (Restore in new window). |
| Bring back the whole group or split | Press Shift+Enter, or open More actions and choose Restore group (N tabs), Restore with split or Restore group and split |
| Copy its address | More actions, then Copy address |
| Keep it past the usual days | More actions, then Keep. The row shows Kept until you forget it. Choose Stop keeping to let it expire. |
| Remove it from Rewind | More actions, then Forget |
| Undo a restore | Choose Undo in the message that appears, or press Ctrl+Z (Cmd+Z on a Mac) on the Rewind page when you are not typing |
Acira says what came back, for example "{title}" restored or 3 tabs restored to {group}. If a tab is already open, it says Those tabs are already open and does not open it twice.
Windows view
The Windows view shows one card for each window as it last was: when it was closed or saved, how many tabs, groups and splits it held, and the sites. Open the card to see its tabs and its earlier saved states.
- Restore window opens a new window with everything in that state, including groups and splits.
- For the window you are in, the card offers to restore only the tabs that are missing.
- Add to this window adds every tab of the state that is not open here into your current window.
- Inside a card you can restore one tab, one group (Restore group) or a selection (Restore these), or go to a tab that is already open.
- Keep and Stop keeping work as in the Tabs view. Forget window removes the card.
- Search finds windows by tab, site or group (Search windows by tab, site or group).
Acira saves a window when you close it, before you close a group or several tabs at once, and every 15 minutes while you work. It also saves the windows you had open when Acira starts with Settings › Tabs › When Acira starts set to Open a New Tab, since only one window opens then. If you have nothing saved yet, the view says No saved windows yet and offers Save now.
What Rewind keeps
- Addresses, titles and how tabs were arranged (groups, splits, order). Never page contents, forms or cookies.
- Closed tabs and saved windows, per profile, on this device.
- Up to 1,000 closed tabs and 500 saved windows per profile.
- Private windows, private tabs and Tor tabs and windows are never saved. Tabs from a locked workspace (beta) are not saved either.
The footer of the page says how long closed tabs and windows are kept, and links to the setting.
Settings
Open Settings › Tabs › Rewind.
| Setting | What it does | Default |
|---|---|---|
| Rewind | Turns saving on or off. When it is off, nothing new is saved. Turn it on from the page too. | On |
| Keep closed tabs and windows | How long: 1 day, 3 days or 7 days. Clearing your browsing history also removes matching items. | 7 days |
| Delete Rewind history | Removes every closed tab and saved window of this profile now. Choose Delete…, then confirm. The row shows how many items are saved. | A button |
Kept items stay until you forget them, even past the number of days.
Limits
- Rewind is not available in private windows. The page says so and shows nothing.
- Rewind saves only on this computer. There is no sync and no account.
- Rewind keeps only the address, title and arrangement. A tab you bring back from the Rewind page loads from its address, so it does not return what you had typed or scrolled.
- Ctrl+Shift+T and Undo bring a tab back with its back and forward history, scroll position and form entries while Acira still holds them in memory: the 24 most recent tabs, for 30 minutes. They are never written to disk.
- If you turn Rewind off, tabs closed before still appear until they expire. New closes are not saved.
- Ctrl+Shift+T and Undo work even when Rewind is off, for the last 50 closed tabs.
- Ctrl+Shift+T can also reopen a private tab, a Tor tab or a tab from a private window that you just closed, as the same kind of tab. Acira keeps up to 50 of them in memory for that window only. They are never listed in Rewind and never saved. Tabs from a locked workspace are not kept.
