Does anyone use Opera browser with quickbooks and did they have trouble with the connect an account.

Hi there, razorbackwater.

Opera Browser isn't one of the compatible or supported browsers for QuickBooks Online. It's recommended to use any of the following browsers to avoid unexpected errors: 

• Google Chrome
• Mozilla Firefox. Note: To preview and print forms on Mac OS, you'll also need the Firefox PDF plugin.
• Microsoft Edge
• Safari 11 or newer (Mac only)

Please see the list of system and browser requirements here:  System requirements for QuickBooks Online, Accountant, and Self-Employed.

Let me know if you need more help with QuickBooks.
