Fix My Google Chrome Extension

Hi, I have a software program that uses a Google Chrome extension to import information about cars from Craigslist, [login to view URL] & [login to view URL] the extension is not working for importing on [login to view URL] because [login to view URL] just changes something on their webpage so now I need the extension updated. I need this fixed ASAP, also the websites change every month or two so I am wanting to find one programmer I can always work with to update it. Thank you! Here is a link to my extension: [login to view URL]
