sometimes it doesn't download. very inconvenient.

Good extension but the user interface is just... terrible... so hard to find the file and format you want to save to, instead you get coloured icons (as submenus? options? different lists?) that you don't know what they are good for. Crazy.

es war das beste aber jetzt nicht mehr wir mussen noch dazu diese app
Video DownloadHelper Companion App 1.6.3

Kept a pre-Quantum version of Firefox along with a previous version of Video Download Helper on a flash drive. This older version gets 5 stars and is excellent.
Sadly, the current version is much less powerful and needs a paid "Companion add-on" to work for many sites. No thanks.
Having to fire up the older version to download around 40% of the videos I want.

Default options are restored after every Firefox restart, I can't change them permanently. Older versions did not have such problem.

THIS IS THE BEST DOWNLOADER I HAVE HAD, EASY TO USE AND EFFICIENT.

The plug-in have memory leak issue when watching live video, using a lot of memory and CPU usage.
