Hi, Firefox can restore your open tabs -- in regular, non-private windows -- using either the first setting on the Settings page or using the menu, either: * "3-bar" menu button > History > Restore Previous Session * (menu bar) History > Restore Previous Session If they are missing or grayed, check either: * "3-bar" menu button > History > Recently Closed Windows * "Library" toolbar button > History > Recently Closed Windows * (menu bar) History > Recently Closed Windows But: Firefox doesn't have a feature to save a list or export a list of your open tabs. You could consider using an add-on for that, or you could save the open tabs as bookmarks (in their own folder). To save all tabs in the current window to a new bookmark folder, you can use either: * Ctrl+Shift+D * (menu bar or Alt+B) Bookmarks > Bookmark All Tabs Any progress so far?
