An excellent ad-on!!!!! The most useful ever... Thank you Mozila for creating this...

The only download addon I found that is consistent and thorough

This works much better than several others I've tried and most likely stick with it.

非常棒，超级喜欢，感谢开发团队！

sa me plais

I am trying to buy a Video DownloadHelper Licence but the buttons are not working.So I cannot even pay for the licence. I just want to get rid of that ugly qr code in the corner. Please publish the working link to buy licence.

Best Downloader - der beste Downloader überhaupt - gibt es leider nicht für Opera!!

works great. the best one i've come across so far.

Cannot download without first downloading a companion app that puts a watermark on the download. I rate as a Piece of Shit!

Works excellent!

muy bueno
