Firefox has options to restore a single closed tab or your entire previous browsing session containing multiple tabs and windows. The options are available through the browser’s History menu -- which automatically keeps a record of all the Web pages that you have visited in a browsing session. Using these options is a convenient alternative to opening a new tab and manually navigating to a closed tab’s Web page. This is especially true if you need to restore the tabs on a previous browsing session with multiple tabs because you can reopen multiple closed tabs simultaneously.
Reopen a Single Closed Tab
Open a new window, then click the "Open Menu" button -- which is three horizontal lines.
Click the "History" icon to display the History drop-down menu. The menu contains a list of the Web pages you recently visited.
Click the name of the Web page that was on the closed tab. If the Web page is not on the list, click "Show All History" to open the Library window. Use the window's Search features to find the tab that has the Web page you want to reopen. For example, click "History," select the date range -- such as "Yesterday" -- that has the tab, and then select the Web page from the list of pages in the right pane.
Restore Your Entire Browsing Session
Open a new Firefox window, then click the "Open Menu" button.
Click the "History" icon to display the drop-down menu.
Select "Restore Previous Session" to reopen all of the closed tabs from your previous browsing session.
Tips & Warnings
- To reopen the tab that was most recently closed, press "Ctrl-Shift-T" on Windows or "Command-Shift-T" on a Mac.
- All open tabs and windows are automatically restored when you restart Firefox after applying a software update or installing a new add-on.
- Firefox automatically reopens all of your closed tabs and windows when you launch the browser for the first time after a crash. If the browser crashes again, click the "Restore" button to reopen your previous browsing session's tabs and windows.
- If you don't close Firefox using the Exit Firefox button, the only tabs that reopen when you restart the browser are the tabs from the last closed window. To correctly close the browser, click the "Open menu" button, then select the "Exit Firefox" button.
