If you're grabbing videos, images, or post text from X for offline reference or archival, this browser extension scans whatever's visible on your current feed, profile, or thread and lets you bulk download it all as MP4s, source images, and text files. No third-party sites or CLI tools. It works across Chrome, Firefox, Edge, and others, includes three free downloads to test the workflow, then requires a paid license. The main limitation is that it only captures what's currently loaded on the page, so you'll need to scroll first if you want deeper threads or longer feeds. Straightforward option if you're building a local archive or doing research and want to skip manual copy-paste workflows.
