Any way to open ALL the windows that were open when Firefox was closed?

I have Firefox set to reopen everything that was open when it closed. That only seemed to work if I had one window open, but I usually have a half dozen or more open with anywhere from a few tabs to well over 100 tabs in a window. The most reliable way I found to have those all reopen was to restart my computer. Firefox would be closed, but next time I opened it all the windows and tabs were there again. I needed to close Firefox a few minutes ago and didn't want to save all the other programs I was in the middle of, so (I thought I had done this before) I right-clicked the Firefox icon on the Taskbar and told it to close all windows. When I opened Firefox the next time it only opened one window (unfortunately the least important one), and only had two other windows in the History | Recently Closed Windows (also not very important windows). Are there any backup or other files where I could get back the other windows I had open? Unfortunately if I have a tab open for a month, for example, it is not saved in today's tabs, and it's not feasible to scroll back through thousands of listings in the history trying to figure out which tabs I had open. Thank you for any assistance!

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox Title bar, especially if you have multiple windows or Private Browsing windows open to prevent losing tabs in unnoticed windows.

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit

In about:config, the following preference is set to 3 by default. If you want more "recently closed windows" in history, you can increase the number. browser.sessionstore.max_windows_undo
