I get an alert when bringing up the internet. The alert informs me that Firefox is not my default browser and asks if I wish to make it the default browser. I choose the option to make Firefox my default browser but the next screen is unclear as to what action to take to complete the transfer to Firefox. The tutorial that is available to assist in this situation has an image of the options menu which comes up when "Open Menu" is selected which has a "General" tab. In the menu which opens on my computer, no "general" tab is available. I downloaded Mozilla yesterday onto my HP desktop with Windows 10 and it seemed to load properly.
