Chrome extension to save data from specific domain pages that user visits

We want a chrome extension that saves title, description information for any page that user visits on *domain.com. Once user opens website, we want them to see a popup screen to write in their username, that username will be added to each url they visit (and script saves) We want two options, one save file, and two username. Save file is where this data will be saved. Username is what this data will be saved as. We want to save it in CSV text format, as - username,date,url,filename,title,keywords I will provide markup in code for each field regarding what needs to be picked and saved per page.
