You can use chrome.storage function from google libraries.
chrome.storage.sync to syncronise the data with your google account
chrome.storage.local for not syncronising.
set is used to set the variables
get is used to take the variables.

to set the variable in one page:

chrome.storage.sync.set({'nameInTheStorage' : jsVariables}, function(){
    if(chrome.runtime.error){
        console.log("Error.");
    }
});

to get the variables in another page:

chrome.storage.sync.get('nameInTheStorage', function(items){
    if(!chrome.runtime.error){
        //do what you want to do with the data
        var x = items.nameInTheStorage;
    }
}
