On my computer, I started using a VPN and I accessed a website like Avast.com (clicked OK on their cookie privacy policy) with Mozilla Firefox after forgetting to clear my past cookies and browsing data (from before using the VPN). Could that website or Avast.com (website server) have been able to track/obtain my real IP info or location through my browser's cookies/previous browsing data (from prior, different websites that I accessed)?

Please excuse my carelessness and ignorance. I am new to this. I don't know much about computers and the internet.
