Youtube Best Video Downloader 2 - MP3 MP4 1080P

Rated 3 out of 5 stars

by KongKing on Oct. 28, 2017 ·

This used to be the best.
But recent versions are less versatile, e.g. they no longer enable downloads using the "Down-them-all extension".
.
I now use and recommend the "YouTube Download Plus" extension. This works very reliably and sweetly, and its easy to figure out what to do despite the Dutch language.
.
Also brilliant is the "Unplug" extension. This has worked perfectly for years on ALL sites with video content, not just YouTube.
P.S. If you value your legacy extensions it is essential that you DON'T UPDATE FIREFOX beyond version 54 (or maybe 55).

This review is for a previous version of the add-on (8.3).  This user has 2 previous reviews of this add-on.

Hallelujah!
For some unexplained reason the app suddenly started working perfectly again.
Its by far the best for YouTube.

Brilliant addon, prior to today.
But now the green Download button has disappeared.
I seems that YouTube have changed something.
Hopefully there will be a quick update.
Restarting Firefox and reinstalling the addon has no effect.
Same thing on another computer.

UnPlug

Rated 5 out of 5 stars

by KongKing on Dec. 4, 2016 ·

Still the best and easiest to use.
Works perfecly with YouTube etc.
The little "fish" icon can be placed in various places using the extensions Options (and customize toolbar).
---
Unfortunately integration with Firefox's Down-them-all (DTA) extension is still broken (since FF44).
But you can still use Unplug to copy the link (from Unplug's dropdown download options). Then just click the + button in DTA Manager (this paste's the link into DTA).

UnPlug

Rated 5 out of 5 stars

Unplug is still the best. "Save as" still works perfectly for all the videos I require.
But saving with the FF Down-them-all extension stopped working with FF44. Hopefully this will be an easy fix asp.
