The module of both this and chrome messing-up with naming rules of all other image downloader extensions I installed and I have to turn it off to fix it.
Consider to make it right on next version release.

Doesn't work on youtube.

Stop deleting my reviews. The latest update DID NOT fix the download panel issue. Most of the time the panel doesn't pop up and when it does, it only offers 360P as a download ... please re-investigate. :( UPDATE: V6.42.50 did NOT fix the problem ... still no pop-up) (V6.52 still nothing - WTF ... can we please revert to a working version like 6.30 ... geesh people!!!)

I bought a piece of junk software for $50 and can't download YouTube.

You've ruined this add-on mozilla! You can't choose the download quality anymore on youtube.
You've shut down the other working add-on to this.
Such a disappointment to a great pc app

在浏览器使用上传时(或取消上传)会自动返回到系统的“上一页面”，它可以是任意软件页面、文件页面等等，只要访问浏览器前访问它，再浏览器上传文件结束后就会立马回到“这个页面”。翻新浏览器后逐步插件筛查，只有这个插件导致的原因。禁用、移除后立刻恢复正常。

Took money, stopped working. Nice.
