Open closed windows

Hello friends
is there an option in Firefox to reopen closed windows all at once?

Is this what you’re looking for –

On the History menu, either:

  • “3-bar” menu button > History > Recently Closed Windows > Reopen All Windows
  • (menu bar) History > Recently Closed Windows > Reopen All Windows

Note: by default, Firefox remembers up to 3 closed windows. If you need more:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste browser.sessionstore.max_windows_undo and pause while the list is filtered

(3) Double-click the preference to display an editing field, and change the value to (for example) 10 then press Enter or click the blue check mark button to save the change.
