Hi there, @msmith1.
Good to see you here in QuickBooks Community. I'm here to help provide some insights about QuickBooks Online (QBO) private browsers.
Internet Explorer is one of the private browsers where you can access QBO. Here are the other browsers which are compatible with QBO:
- Google Chrome.
- Mozilla Firefox.
- Safari.
When using a private browser, make sure to clear your browser's cache to start fresh and remove the previous browsing history and network. To do this, you can check this article for the detailed steps: How do I clear my browser cache and temporary Internet files?.
Please know that you're always welcome to post if you have any other questions about QBO. Have a good one.
