Hello! Firefox will update itself automatically when a new version is available. To check for updates, follow these steps: 1. Click the '''three lines''' on the right side of the taskbar, 2. Select '''''Help''''' from the drop-down menu, then '''''About Firefox''''', 3. A window will open that says '''checking for updates''', and if they are available, they will be installed, and then Firefox will tell you to restart the browser. '''WARNING: If you use the option below, you risk not loading your old default profile anymore! If you want to fix this, you should go to the Firefox configuration files! ''' If you want to manually download the new version, go to the '''official Mozilla Firefox website''' and download Firefox again, then '''reinstall Firefox with the installer''' that will be downloaded to you. I hope this helps you! Vexi
