Stopped working sometime in late 2022. It used to work nicely as described, but no longer does the "little red button" appear. Last updated in May 2020 which is about when I first installed it.

Kein Audio download mehr, nur 2 -mp4 Optionen. Hätte mich auch gewundert, wenn Audio mal funktionieren würde...

ghfgh

No aparece el boton para iniciar la descarga

Very good WHEN IT WORKED. i thank its creator but as of late (FFox v80+...@82) not working.

Trying "Y2Mate" by Y2Mate (i'm not connected to either AppOn/AddOn) for a similar FREE FFox "AppOn" (loads as mini green button under VID. The bit more work as to Y2Mate is one has to click on the circled "i" icon to see file size. Still will check back and recommend others do so to support the creative mind of such people that take their time to create apps for all.

Stopped working. I sent an email a couple of weeks ago. No answer as of today. Shame

I have downloaded this Extension in order to download the Highest Quality possible. Althought It can download the 1080p FHD video, but MUTED, with NO sound. In Comparison to the "Video DownloadHelper" which can convert and download sound, but again they have a watermark on the final video...
