In the Options screen, select General category from the left side.Click on the menu icon in Firefox toolbar and select Options from the menu.Here is how you can make Mozilla Firefox browser restore all the tabs automatically at start:
With a little setting in Firefox, you can make Firefox restore the previously open tabs or previous session so that when you start Firefox next time, it reopens all the previously open websites. Next time you use Firefox again, you have already forgotten all the websites that you had found. In these times, you have to close Firefox, shutdown Windows and leave the computer for hours. For example, you are researching about how to make the old game Quake 2 work in Windows 10 and then the time comes to leave your comfy home for work. Sometimes when you are in the middle of doing something in Firefox, something else comes up and you have to attend to it.
