Browsers crash, updates restart them, and sometimes you close the wrong window. If that window held an afternoon of research — twenty tabs of sources, a half-written comparison, a booking you hadn't finished — getting it back matters. Here's what each browser can do on its own, where that stops, and how a session manager fills the gaps.
Built-in options in each browser
Chrome
- Reopen closed tab or window:
Ctrl+Shift+T(Cmd+Shift+Ton Mac) reopens the last closed tab or window, repeatedly. - History → Recently closed lists closed windows with their tab count.
- Settings → On start-up → Continue where you left off reopens your last session after a restart.
- Bookmark all tabs:
Ctrl+Shift+Dsaves the window into a bookmark folder.
Edge
- The same
Ctrl+Shift+Tand Recently closed list as Chrome. - Settings → Start, home, and new tabs → Open tabs from the previous session.
- Collections can hold pages, but you add them one by one or via “Add all tabs to a new collection”.
Firefox
Ctrl+Shift+Tand History → Recently closed windows.- Settings → General → Open previous windows and tabs.
- History → Restore previous session after a restart.
- Bookmark all tabs from the tab context menu.
Where the built-in tools fall short
- They only remember the recent past. Recently closed lists are short and are cleared over time.
- No names. You can't keep “Client A research” and “Tax return” as separate sessions to reopen whenever you like.
- Crashes and profile problems can wipe the restore data along with the session.
- Bookmark folders are frozen. Updating a saved set of tabs means deleting and re-saving.
- Tab groups are only partly preserved across all of these.
- No sync of sessions between computers in a way you control.
Using a session manager
Super Session Manager is a free extension for Chrome, Firefox and Edge that turns windows into named sessions you can reopen, update and back up. It's built by the same developer as Web Archive Viewer.
- 1
Save a window
Open the popup, type a name and save. Click the tab count first to preview every tab and remove the ones you don't want.
- 2
Restore it later
One click reopens the session in a clean window with the original tab order. Sessions over 20 tabs restore with tabs asleep until you click them, so an 80-tab restore doesn't freeze your computer.
- 3
Keep it up to date
Add the current window or a single tab to an existing session, or replace its tabs with what's open now. Saving under a name you've used never overwrites — the new one becomes “Name (2)”.
- 4
Let it back you up
Automatic snapshots save your open tabs every 5, 15, 30 or 60 minutes, with a live countdown to the next one. Free keeps 3 snapshots; Pro keeps up to 100.
More than saving: organising sessions
| Feature | What it does |

| Favourites | Pin important sessions to the top (1 on Free, unlimited on Pro) |

| Archive | Move old sessions out of the way without deleting them |
| Search | Find a session by name, URL, domain or page title |
| Tab groups (Pro) | Save and restore Chrome tab groups with names, colours and collapsed state |
| All windows (Pro) | Save every open window into one multi-window session |
| Encrypted cloud sync | Sync sessions to your sessionmanager.net account (5 on Free, unlimited on Pro) |
A note for researchers
Sessions keep your *tabs*. They don't freeze what those pages *said*. If a session is full of sources you'll cite later, archive the important pages too — then the content is safe even if the page changes. See how to archive a web page permanently and how to cite an archived page.
FAQ
How do I save all open tabs in Chrome?
Press Ctrl+Shift+D to bookmark all tabs into a folder, or use a session manager such as Super Session Manager to save the window as a named session you can update and restore.
How do I restore tabs after Chrome crashes?
Chrome usually offers a Restore button on restart; otherwise check History → Recently closed. A session manager with automatic snapshots lets you restore from a backup taken minutes before the crash.
Can I sync sessions between computers?
Super Session Manager syncs sessions to your account with encryption: 5 sessions on the free plan and unlimited on Pro.
