Thank you for contacting us here in the Community, kandywmabry.
I'm glad to clarify this situation. These two programs have different features and functions.
The option to open several pages in QuickBooks Online (QBO) is to right-click a menu, then select Open link in new tab. This way, you'll be able to switch and work on your task by switching between those tabs.
Please see the attached screenshot below for your guidance.

Check out the different features that are designed to improve the way you run your business with QuickBooks.
Keep me posted if there's anything else you need in QBO, and I'm happy to help you out.
