I had a slightly different approach based on your extension's accessible html pages.

Add your page to the manifest:

"web_accessible_resources": ["variables.html"]

Create your page (here, variables.html) and extract the content's data (i.e. window.contentVar):

Access from your extension's JavaScript:

var myVarName = $("#my-var-name").text();
