Chrome Extension: Build Features, Debug Existing Issues

We are looking for help with our existing Chrome extension, which adds a central shopping cart onto the websites of many retailer websites. Specifically, we are looking for the following work to be done: 1) Bug: When an existing partial order is deleted from the database, the Chrome extension doesn't sync properly 2) Bug: Product quickview for [login to view URL] is having issues displaying our Add To Cart button 3) Bug: Some products can not be added to cart for the [login to view URL] retailer 4) New feature: On the cart confirmation page, if user does not have a credit card on file, replace inline credit card form with popup window 5) New feature: Automatically gather metadata (style, size) for products, when adding product to cart. Remove the existing screenshot function. 6) Bug: The chrome extension is incompatible with a few other chrome extensions and webpages who load similar javascript functions. The project is on Github, and we are using Trello for project management. Full details regarding the project tasks are in the attached document below. Thanks!
