serpapps/twitter-x-downloader — reverse-engineered prompt

Build me a simple browser extension for X that lets me save what I can already see on the page without using a separate website.

I want it to work on feeds, profiles, and threads. When I open the extension, it should scan the posts currently visible on screen and find videos, images, and post text. Let me review what it found in a clean popup, then download items one by one or grab everything visible at once. Videos should save as MP4 when available, images should save in their original format when possible, and post text should export as TXT files. It would also be great to have quick buttons right on posts for faster downloads.

Please keep it easy to use for normal people, and make sure it only captures content that is actually loaded and visible in the browser. Saved files should go to the normal Downloads folder and feel organized enough for offline reference, research, or archiving. If needed, look up current browser extension docs online.
