I honestly don't think the problem is with the extension. Because even when I completely disable the extension and download directly from your website at http://en.savefrom.net and enter ANY YouTube link, the results are exactly the same:

Could you please try go to the website yourself, enter this sample link www.youtube.com/watch?v=frdj1zb9sMY and try downloading the 360p file and see if you get different results? As for me, I always get "videoplayback.mp4".

Thanks again for your assistance, Aleksandr!

Thank you very much again for your reply. I followed your instructions precisely. Unfortunately, however, it did not fix the problem. The results are still the same. 720p filenames are okay, 360p are still videoplayback.mp4. I really hope you have some more ideas about how to fix this issue.

Here is a sample:

http://en.savefrom.net/#url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dfrdj1zb9sMY&utm_source=userjs-chrome&utm_medium=extensions&utm_campaign=bookmarklet

When I right-click and save link as to download the 720p version, the filename is:

Rogue One_ A Star Wars Story Trailer (Official).mp4

When I try to download the 360p version, the filename is "videoplayback.mp4"

• Browser: Chrome 55.0.2883 Windows 7
• User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
• Extension: userjs-chrome 6.92.2

I use Tampermonkey. However, even when I download directly from savefrom.net, the 360p links still assign the default filename "videoplayback.mp4". As I mentioned, this only started happening about 2 months ago. Thank you for your help. I really hope you can resolve this issue.
