Although QuickBooks Online is a web-based service, it also depends on the processing speed, RAM size, and Internet connection bandwidth of your computer or device to work seamlessly. The program's execution might be impacted by a deficiency in any area. That said, you'll want to check that your system meets the basic requirements to help narrow down the reason for slow performance.

To get started, open your QBO company through a private or incognito window using these shortcut keys:

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

If that works, go back to your main browser and then clear the site data to start over fresh. Alternatively, we can switch to other supported web browsers.
