I struggled with it at the beginning. Downloads were imcomplete aborted. Once I increased the timeouts significantly and reduced the number of parallel downloads everything was working nice. If you have trouble with this Plug-In have a look at its Behaviour preferences.

This app worked perfectly for ONE month. Then never worked again. It is worthless and I suggest not wasting time with it.

a very good video downloader with many download option and convert option.

Very nice and cool.

This was brilliant in the early days, then went through some changes due to FF changing. It is now back to being excellent. The queuing of files and limiting downloads helps a lot, the speed is generally good. The only issue I now have is, if you download several videos, then wish to cancel them, you have to do it item by item. Needs to be a way to select more than one and abort. Simple to use and to set up.

Essential bit of Kit for browsing experience. Excellent app in all respects.

Ótima extensão. Grata.

Nice Keep up the good work

Although it doesn't download all sites it's still the best in my humble opinion of all the "Extension" Downloaders in that it seems to work on between 92-95% of times I've successfully attempted to use it. Thanks

Ça marche bien

This add-on is useless and confusing. When I tried to use it, it asked me to submit a URL address. It opened a new tab and gave me the following message "You have to setup a suitable URL for your favorite downloader service. You can use the variable {url} to forward the currently viewed video URL to the downloader service." I don't understand this message and can't understand how this could be a reasonable way of setting up a download service. Nor do I have an URL address to submit to them. What does this mean? There is no explanation, nor supporting page or introduction. I've decided to delete the add-on even though FF recommended it. I'm assuming they made a mistake.

Muy buena extension, me ha salvado de varias ja
