I am trying to find a video on How to make Firefox start when Windows startup? There are instructions on how to do it but I get confused really fast. I like videos to show me. you have to do that in Windows 10 autostart folder in the start menu. You can do that by: 1. Press the Windows Logo Key + R, type shell:startup, and then select OK. This opens the Startup folder. 2. find the app you're looking to add or remove, and drag and drop it in the folder or copy it, then Paste the shortcut to your app into the Startup folder to have it run at startup.
