Hi Luis, you can do that! Here are two options: (1) Set the home page setting to include multiple tabs. But be aware that they also will be loaded each time you launch a new window (Ctrl+N). More info: [[How to set the home page]] (2) Pin tabs that you want restored at startup. Be aware that clearing history when Firefox closes (or using "Never remember history") isn't compatible with this feature. More info: [[Pinned Tabs - keep favorite websites open and just a click away]] Note: if you accidentally close your window with the pinned tabs before you close another window, restore the important window using Ctrl+Shift+N (or, menu > History > Recently closed windows).
