So far for my needs, this is the best and fastest video downloader ext that i tested. the only cons i found is that you can't setup a default video res for download (everytime i download i need to manually select the video res, cause the ext always select the lower one.) So, instead of just hitting the download button, everytime i need to "setup" the resolution first. I understand that video and sources can have several types, but an option like "donwload the highest res possible" would make this ext trully the best.

Gosto muito pois é simples pra fazer o download, já identifica que existe o vídeo na página, ou basta dar play no vídeo pra a extensão identificar o vídeo, pode escolher a resolução.

great

This extension used to work wonderfully. Of recent however, it seems, more often than not, to not merge the audio & video streams for video downloads. This bug was accepted a while ago [Ticket#425947] but no remedy has yet been made available.
From time to time it also seems to think gmail email or calendar webpages are worthy to "download"!! Of course, trying to play the downloaded result fails - most recent example is a calendar web page display downloading as a BIN file.
I will update my rating once these issues are resolved.
NB: another support page lodgment has been provided with further details on the separation issue 15Jun20.

I have used Ant Downloader for 4+ years, and have found it to be the very best of add-ons. They are a high-quality and honorable company, and I would put them in my top 5 web organizations. Thank you ANT DOWNLOADER
