Thanks for getting back with the Community, knoxfarm2020.

Intuit's internal browser for QuickBooks is up-to-date with the latest critical security updates and will continue to be updated as necessary. It isn't based on any third-party web browsers and is fully custom.

Here's some of the browser's technical specifications:

• HTTP end-points are blocked due to security reasons.
• Accessing QuickBooks data with ActiveX is allowed only with user consent.
• If an SSL certificate expires, the page isn't blocked from loading. Instead, an unlock message signals expiration and can continue to load it.

I've also included a detailed resource about working with your internal browser which may come in handy moving forward: Use the built-in browser

Please don't hesitate to send a reply if there's any additional questions. Have a wonderful day!
