Assuming you declared tabs permission in manifest, there are several problems with this code:

• list_session() function will return empty list because you modify the list in a callback function, which could be called by chrome 15 minutes after your console.log(list); and return. You need to change your program structure to use callbacks instead.

• concat method does not modify original array

function list_session(callback) {

        var list = [];
        for(var i=0;i
