works well at detecting and downloading videos that other addons fail to detect. I would like to give it 5/5, but - it is extremely resource hungry. I have an Intel i5 system and this addon maxes out 2 entire cpu cores to 100% whenever it is downloading using the companion app. marking it down by 2 stars for that, 1 for each core that it maxes out. there's absolutely no reason for cpu usage to be this high just to download files.

also, the companion app is necessary if you want to download multiple files (otherwise it just queues them up in the firefox downloader, which is a bit rubbish) but the only way you can interact with the app is through the firefox addon interface, which isn't great. would be really good if there was a way to pass the downloads on to the download manager of our choice, and not just to the firefox bare bones downloader - that would be ideal.
