A popup reloads it's document every time it's closed/reopened. Instead, you should use a background page to preserve state.

General way to do this is:

1. communicate from popup to background to do something. I.e.: do an ajax request and store the result in a plain javascript object.
2. do a get from the background page, to get the javascript object. Even though you close the popup, state is preserved in the background page.
