It takes you to a webpage laced with ads and suggests it is downloading something, but no download appears in the default download directory and there's no file that I can find. I hope that I haven't installed something I should not have. I've uninstalled it now, anyway.

完比沒用

Funciona muito bem! Excelente extensão para download de vídeos vimeo.

Very Nice, User Friendly, Please develop YxxTube Downloader!

Lo mejor mejor de lo mejor

This actually works, as opposed to every other extension I've tried.
Also, it did not ask for unneeded permissions!

Works as intended

Does not work on Vimeo channels.

Worked fine for the one file that I downloaded so far. There are minor cosmetic improvements that I would like to suggest:

1) it should be possible to undo an "Automatically select quality" setting (i.e. completely remove it without toggling to a different setting)

2) The icons used on the download screen are not that self explanatory and they should provide some tool-tip text

3) the plugin's tool-menu (see plugin's icon in Firefox's toolbar) seems to list duplicate video entries that should better be filtered out (no big deal since download buttons are also directly available in the video's widget)

Tried to download a Vimeo video. It opened a webpage and something seemed to be happening, a progress bar went from 0 to 100% slowly. At the end, the progress bar said 100% and nothing happened after that. No clear process of what to do. Help information for the addon was very vague and didn't help. Not sure if I'm missing something or if this is a garbage plugin.

I clicked download (1080p) again and the same process happened, again without a video file given or without a "your download is ready click here to get the file" kind of message. Confusing addon. Also has ads and such that make me nervous about using it. Seems sketchy.
