Hi there, @handytom. I'm happy to assist you in opening your QuickBooks Online account in a regular browser.

We appreciate you doing the clearing cache and cookies on your browser, but since you've mentioned that the issue persists after doing the troubleshooting.

As there are no outages with QuickBooks Online, it can be opened on other browsers instead. I suggest contacting IT support to check the settings of your desktop or computer since you mentioned that this is only happening on one of your desktops.

In addition, I'd like to share this article with you if you want to learn how to input your expenses: Enter and manage expenses in QuickBooks Online.

Don't hesitate to leave a reply if you still have questions about your QBO account. Have a great day.
