Hi,

You can try to right-click and Modify the value of browser.sessionstore.max_windows_undo in about:config.

  1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise!, to continue to the about:config page.

Note that Firefox always seems to remember at least one closed wind even if you've set the above mentioned browser.sessionstore.max_windows_undo pref to 0. That can be a problem with pop-up windows that won't allow to open additional tabs or close existing tabs without closing the window.

Hi dumdidadida, Thanks a lot for your help. It was "right in the target". I can know undo until 10 "recently closed windows".
