L'extension fonctionne très bien. En revanche, elle cause d'énormes problèmes de performance sur twitch depuis au moins 4 ans. Il serait temps de s'en occuper.

The addon works very well. However, it causes huge performance issues on twitch for at least 4 years. It's about time to take care of it.

Some days it works, some days it doesn't - 'can't download' - frustrating!

it is very easy and can capture most of the times my issue is errors that has no details about which file it happened to and if you close the browser you lose everything in the queue which is crazy

can't download videos on bilibili

it's ok for some things but can be pretty flaky.

Often it requires the companion application... which is not such a big deal, but even then it can still be distinctly unreliable.

I have a Video Downloader app on my android phone which does a far better job, is much more dependable, saves in sensible formats, offers a better choice of download resolution options, in a much easier to follow way.
The android app also does simultaneous multi-downloads of the same files so you can download a big file in five minutes on the phone what take this addon twenty minutes to do.
By comparision if that android app got a 10/10 rating - which by my book, it does, this barely gets a 3/10.

I regularly have to just give up in disgust at this add-on's inability to save files and switch over to my phone.

Also I've downloaded files using this addon to discover they are in a ridiculous webm format - absolutely not useful to me at all, whereas the android app saves using the much more standard MP4 container.

The app developer really needs to take a long hard look at the alternatives and up their game if they wish for this addon to stay relevant.

helpful!
sadly can't handle a poor network by being able to reconnect/start

It used to be a lot better. As in the previous build just a week or two ago. Sites I've used it on forever, it no longer activates for or even lights up. Something as simple as downloading from DepositFiles, the final step after captcha, it would light up, let me copy the url so I could put it in a download manager. Now it just sits there dead, not reading it right. And certain other tube sites and whatnot, no longer works.
