Positive is that VDH grabs videos that other link grabbers don't. Negative is that there is no protokoll of downloaded or queued files. Everytime Firefox crashes I don't know which files are lost. If the download had begun there is an incomplete file in the download folder. But not if it was in the queue. Sadly Firefox crashes sometimes when there are several downloads in the queue of VDH.

コンパニオンを導入した場合。
無料版は、動画にロゴを入れるために無駄な再エンコードをします。CPUが多く使われます。
YouTubeやニコニコ動画を開いたあと、何もしていない状態でもCPUが１００％に上昇することがあります。
Javascriptがタスクマネージャで動作して暴走しているのが見えました。
それを削除すれば平常に戻ります。
しかし、Javascriptが動作していなくてもCPUが１００％になることがあります。
Video DownloadHelperを無効にして、動画を閉じると平常に戻ります。
そのため、私は通常、Video DownloadHelperを無効の状態で使っています。

Just got the automated message that I downloaded my 200th video. This add-on is awesome! The interface could be a little more user-friendly though, cause often there are WAY to many download-options to choose from (some completely useless), hence "only" 4 stars

I have found this add on very useful. It can be a bit slow and it doesn.t always manage to download a playable video but mostly it does and the ease of use makes it a good addition.

A real HELPER! Thank you.

I’ve been using this add-on for years and years and it’s been absolutely wonderful. A very quick and easy way to stash videos away to be watched later.

Nice: Just one click for capturing audios on web sites. I haven't tried other functions yet. The user interface is a bit hard to understand for me. I'll need more time to dig in and play around with it.

Las descargas muy bien, pero es un poco confuso a la hora de identificar los archivos a descargar-

PARFAIT

Its OK.

Works 90% of the time very well. One of the tools I use most.

Efficace. Quelques problèmes de fonctionnement, ne marche pas avec certaines vidéos (rares).
