Web browser sandbox file and location

Avast Free Antivirus / Premium Security

Where can I find the folder that Avast sandbox uses to save web browser info?

Thanks, Lawrence

Files will be gone as soon as the Sandbox closes.

something is being saved somewhere, because the history of links is still there when reopening the browser in the sandbox. I am having trouble getting Firefox or Chrome to work in the sandbox at the moment. I am running Win 7 and Avast premier.

Thanks for your reply, Lawrence
