以前能用来着，这两天是因为B站的AV号改BV了所以用不了吗？我这里直接找不到可下载的文件了，（好吧，我刚才看了url，确实没有bv，希望能尽快更新，感谢！）

哥啊，点下载怎么蹦出来的网站打不开啊，也没提示开始下载，下载到哪都不知道啊，这是不是得翻墙？

无法下载视频，最终下载的是一个几百k的HTML，指向403错误

只能下载几百K的文件。
FLV显示的大小倒是正常，但下载还是几百K的
此外，每个清晰度有两个选项，一个是大小不对的视频，另一个是html网页

Mac系统，火狐最新浏览器，无法正常使用插件，每次点击下载跳出来一个只有十几字节的fiv格式的下载文件，作者可以留下微信吗

不知道为啥，用不了，html播放器，点击扩展的清晰度后跳转到了一个界面，上面一个0%的黄色条，下载列出了各种清晰度和音频，我选flv但是边上的下载图标点击没反应。如果开发者有空闲的话可以回复我，或者附上联系邮箱。

我点了好几个视频都下载不了，都是下载几kb的文件，另外影视或者番剧也如此，例如这个av32830456

下载不了，等半天也没反应，下载界面根本出不来

It doesn't work.When I watch the video on Bilibili, it will not actively sniff the playing video.When I manually enter the URL of the video(for example:https://www.bilibili.com/video/av56013914),It will show "No download file found. Install the browser extension then try again".When I remove the prefix from the URL(for example:bilibili.com/video/av56013914) to try again,this extension will not respond. It seems that it has been loading but has no result.I used the extension you developed to download several videos in a row, but it all failed.I am in mainland China.My Firefox version is 52.90, and my operating system is Windows XP. I don't know if it's because my browser version is too low. I hope you can contact me after seeing my feedback.

兄弟，你这工具简直太强大了，速度又快，过年啦！

不能用了，下载下来的都是一个 254kb 左右的文件。
It doesn't work now (FF 71.0). What you really download is a fake FLV file whose file size is around 254kb.

好用，速度也很快
