The guy(s) try to do the best, this is my review in support of their work - really good - Too bad that apparently Facebook videos do not worked lat time I tried although FB is ubituquous nowadays

It does what it was intended for, which is downloading videos in MP4 and other formats. However, for each video chosen for downloading, it shows one link with actual video size and another link with video size of 0 which is not only inaccurate, but unnecessary and confusing. I fail to see what the purpose of the redundant and inaccurate download option is.

Works 8 out of 10 times.

Helpfull tool

OK, good

Whenever I need to download a video I will reach for this extension or yt-dlp, and one of them usually gets the job done. Fantastic piece of software.
EDIT: It seems nowadays a QR code is getting added to downloaded videos on some systems. It does not happen to me, but if it's the case that's a pity. Also I kind of dislike that the extension itself is not FOSS.

good!
