How to restore tabs in Firefox

The simplest way to restore tabs in Firefox (what to do if your Firefox tabs disappeared)

Click the Library menu in the top-right of Firefox > History > Recently Closed Tabs or Recently Closed Windows.

If that doesn't work, try this instead:

Click Open menu in Firefox (top-right menu) and select Library > History > Recently Closed Tabs or Recently Closed Windows.

If neither of those options work and you still need to restore your Firefox tabs:

Use this volunteer-created session history recovery tool at your own risk. You’ll grab your session history files from your Firefox profile, input them into the recovery tool, and export the URLs. Here’s how:

  1. Click Open menu in Firefox (top-right menu) and select ? > Troubleshooting Information.
  2. Type or paste about:support in the address bar and press Enter.
  3. In your profile folder, double-click into the sessionstore-backups folder. Save all files here to a safe location, such as Documents or Desktop (you can go back and delete these once you’ve recovered your tabs).
  4. Look for files with a .jsonlz4 or .baklz4 file extension. Upload those files to Session History Scrounger and follow the directions.

How to save tabs in Firefox

Use Workona to save and manage Firefox tabs

If you’ve lost your tabs, we suggest using Workona for one simple reason: it saves your tabs automatically. Other methods require you to click a button to save your tabs. Yes, it’s just one button—but if you forget, you could lose days or weeks of work, depending on how long you’ve had your tabs open.

Workona also allows you to organize your tabs into separate groups, called workspaces. This means you can stay organized while you work on all sorts of different projects.

Other methods for saving tabs in Firefox

You can use Firefox bookmarks to save tabs. Warning — this method is pretty clunky and requires you to manually save your tabs anytime you make a change. Here’s how:

Select Bookmark all tabs from the Bookmarks menu at the top of your browser. To bookmark tabs individually, use the keyboard shortcut Cmd + D (Mac) or Ctrl + D (Windows), or you can click the star icon in the Firefox address bar.

If you’re constantly closing your tabs by accident, be sure you keep this dialog checked (you’ll see it when you try to close Firefox with tabs open).

  2. Click Preferences.
  3. Under General > Startup, check the box labeled Warn you when quitting the browser. You may also want to check Restore previous session.
