Hello @donkiely,
I appreciate you for getting back and providing clarification about the issue. I'm here to help you figure out the cause of the blank pop-up in QuickBooks Online.
You're right. It's a pop-up within QuickBooks and not related to your browser settings.
I've reviewed the thread and see that you're experiencing a blank window when navigating the product. You can perform some basic troubleshooting to isolate and fix the problem.
Since you're getting an unusual result with the display, your browser's stored cache may be full. It can cause unusual behavior to the visuals when exploring QuickBooks or viewing information.
I suggest logging into your account using a private browser or incognito mode. It doesn't store data in the cache and is a great way to check if it's the blank pop-up is happening to a specific browser only.
If you're using Mozilla Firefox or Microsoft Edge, press the CTRL + Shift + P shortcut on your keyboard. For Safari, hit Command + Shift + N. Press CTRL + Shift + N if you're using Google Chrome.
From there, log into your account to determine if you still get an empty pop-up. This way, the information will reflect from the window.
Ideally, in-product tips appear to new users accessing the features for the first time. There are no specific settings to disable them within QuickBooks Online.
If it works, let's clear your browser's cache to have a clean slate and function efficiently. In case private browsing doesn't work, use another supported web engine to get the best and most secure experience.
Additionally, I've attached this article you can visit about how to change settings and turn on features: Edit company settings in QuickBooks Online. It also contains details to personalize QuickBooks to work the way you want it.
Please let us know if you need anything else regarding getting rid of blank pop-ups or fixing unsual behaviors in QuickBooks. Keep safe always.
