Do niczego ten dodatek. Nie potrafi pobrać i połączy streamingu w kawałkach, np. stąd https://playpuls.pl/obyczajowe/lekarze-na-start/vod/lekarze-na-start-odc-1-s0-e1

I cannot find it

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.

It won't let me download/install claiming I'm running older version 54 when in fact I have the most current version 76!

Ant Video Downloader used to work really well to download videos from a variety of websites but in the last 2 years it has become so unreliable that the majority of videos will either fail during the download or download in extremely low quality when they appear in full HD on screen. Sometimes if you keep refreshing the page and re-attempting the failed downloads they will eventually work. This makes it very frustrating to use and difficult to download videos so not sure what happened to it. For anyone looking for a solution that works, Download Helper seems to do the job and reliably download videos from all the sites that used to work with Ant but now do not.

Downloads only 4 min.
