: This extension supports high resolutions, including 4K and Full HD, and allows for quick conversions to MP3 or MP4 formats with a single click.

: A powerhouse for media extraction, this tool works on thousands of sites beyond YouTube. It can detect multiple streams simultaneously, making it a viable choice for users who want to grab various videos from a playlist page one after another.

: Specifically designed for bulk actions, this extension can scroll through an entire playlist to "scrape" all video links and trigger automatic downloads. Advanced "Power User" Methods

: One of the most stable and long-standing options, this extension adds a simple "Download" button directly to the YouTube interface. While highly reliable for single videos, it is often cited for its consistent performance and ease of use when navigating channel content.

: For those who prefer using external tools like VLC or dedicated download managers, this extension scans a playlist page and generates a text file of all video IDs. This file can then be pasted into a batch downloader for massive, hands-off saving.

Choosing the right extension depends on whether you want a built-in solution or a bridge to more powerful external tools.
