I need a FB video downloader that support HD videos, any suggestion?

Once I saw a high-definition documentary clip on Facebook and wanted to download it for my collection. But I looked for several online facebook video downloader tools at the time, but the video was either blurry or the download speed was limited, which was really annoying. Later, I researched and found that I could actually download Facebook videos using the browser developer tools, and they were original high-definition files, without installing any software at all!

The method is actually very simple. I did it in Chrome:

1. Open the Facebook video, then press F12 (or Ctrl + Shift + I), and the developer tool interface will pop up.
2. Switch to the "Network" option, then click "Media", the page will be blank at this time, but don't worry.
   Play the video, and you will see an MP4 link appear!
3. Right-click to copy the link, paste it into a new tab, and open it directly. Then right-click > Save As, and you can download the high-definition MP4.

The whole process takes no more than 1 minute. The key is that the quality of the downloaded Facebook video is original, without compression, which is much better than most download tools! I have been using this method since then and it has basically helped me with most Facebook videos. I recommend you give it a try.
