A cornerstone extension to using a browser for the Internet. Who with a thinking mind can do without it? Annoyed at how often I have to reinstall due to browser updating that does not consider Addon Creator's efforts. Without this addon the use of Firefox would not be the same.

Just be looking at the number of users you can tell how good this add-on is!!

Very very good.... Thanks

One of the best feature provided by Firefox.
In today's OS, no one can match what Google, Chrome and Firefox did for the internet society.
In the Cyber World hall of fame, they should accord Google, Chrome and Firefox an accolade for their contribution to the cyber world at large.
Aside from the benefits they provide to the world UNESCO should also accord them as a Ambassador in the cyber world communities.

This extension is the best media downloader of the many I have tried. It works with virtually any site that has Video or Audio. The interface is simple and intuitive.

muy buena

Muy bueno y estable para descargar.

ótimo programa

I've been using DownloadHelper for YEARS! By far the BEST and most reliable addon to date! They do a great job at keeping it updated. It picks up more than just youtube videos. it's really easy to use too! Honestly, if you're looking for a downloader, this is the one to look get.

great

به این دلیل که هیچ هکری نمی‌تواند به راحتی وارد فایرفاکس شده وازآن سو استفاده کند

I downgraded to Firefox 56. The new Firefox Quantum is a bag of sh*t anyways, and installed previous version of the plugin. All good.....so far.
Thanks for the plugin, and sorry for recent user complains.
Folks, just downgrade to FireFox 56.
