Most establishedA long-established browser extension for downloading video from a very wide range of sites.
Strengths
- Very wide video-site coverage built up over many years
- Available on both Chrome and Firefox

MediaGrabber Pro vs Video DownloadHelper3. DownThemAll!
Best open-sourceA free, open-source download manager and accelerator that can mass-download links and files from a page.

MediaGrabber Pro vs DownThemAll!4. CocoCut
Best for streaming videoA Chrome and Edge extension focused on detecting and downloading video, including HLS (m3u8) streams that it merges into MP4.
Strengths
- Detects HLS (m3u8) streams and merges them into a single MP4
- Pick the quality and preview before downloading
- No account needed to start
Trade-offs
- Video-first: not built for bulk image grabbing
- Free version has speed and length limits
Best for: People who mainly need to save streaming (m3u8) video from the page they are on.
MediaGrabber Pro vs CocoCutWhat about online downloader sites (y2mate, SaveFrom, etc.)?
Online downloaders can be handy for a one-off, but they come with trade-offs: you paste links into an ad-heavy page, the video is often processed on someone else’s server, and quality or speed may be capped. A browser extension detects the video right where you’re watching and downloads it locally — fewer ads, more privacy, and no copy-pasting. If you download more than occasionally, an extension is the better habit.
