eBay Description Checker Extension

I regularly create eBay product listings in Chrome on my Mac and usually keep several listing tabs open at once. I need a lightweight Chrome extension that, once switched on, keeps scanning every open tab in the current window. When it detects that the eBay description field (the main text box in the listing form) is no longer empty, the extension should: • wait roughly 1–1.5 seconds, • capture the tab’s URL and add it to an internal list that I can later copy or export, and • close that tab automatically. The extension must stay active in the background so I only enable it once per Chrome session and let it run. No support for other browsers is required—only Chrome on macOS. Deliverables I need: • A completed, ready-to-load unpacked extension folder (Manifest V3 preferred) plus a compressed .crx if possible. • Clear installation and usage instructions for macOS. • Source code with concise comments so I can adjust the wait time or output format later. Once the extension can consistently detect the description field, record the link, and close the tab without affecting other open pages, the job will be considered complete. Ideally, the tool should also be able to reopen the completed list of links (preferably in a new Chrome window) and display the products.
