Why doesn't the authentication page work when Firefox's enhanced protected is enabled?

I'm here to help, craibuc.

Let's perform some basic troubleshooting on your browser to isolate this authentication process. Let's begin by accessing QuickBooks Online in a private browser. Since this type of browser doesn't store cache, it's easier for us to identify if this is a browser issue.

 Follow these keyboard shortcuts to start an incognito session:

Here's how:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N
• Microsoft Edge: Ctrl + Shift + P

If it works, you may want to clear the browsing history of your regular web browser. This will remove previously stored browsing data that might have caused the issue. Otherwise, you can try using other supported browsers to be thorough.

If there's anything I can help you with QuickBooks, please let me know. I'm always around here in the Intuit Community to help.

Firefox, in private mode, with protection enabled.  See attachment.

Thanks for the prompt response, raibuc.

I appreciate the additional information you have given regarding the authentication process not working while on a Firefox enhanced protection mode.

Let's enable the pop-up blockers as this can be the reason why the authentication page didn't work.

Here's how:

1. Select the Menu, then choose Options.
2. The Options window will appear; select the Content tab.
3. Go to the Pop-Ups section and uncheck the box or select the Exceptions button and add qbo.intuit.com as an exception.
4. Select Save Changes.
5. Once adjusted, log out, close Firefox, reopen it and log back in.
6. Try accomplishing the task you were blocked from before.
