Very good for data saving, could be better if supports fenix

Excelente para descargar videos.

非常棒！在Firefox预下载之前会弹出提示，避免流量浪费。目前还准备找找有没有拦截自动打开外部app的扩展……

This is so much nicer than the tiny alert pop-up at the bottom of FF that quickly disappears. I would have given it a 5+, but for me, it opens two tabs, rather than one. The first is about:blank and the second is the confirmation dialog. Two suggestions: 1) add a link to the confirmation dialog to open about:downloads to allow a user to view and delete downloads; 2) Allow the user to change FF download location from internal to the external sdcard. I manually did this by adding browser.download.dir and pointing FF to the dir on the sdcard. This is a MUST HAVE addon for FF for Android. I am so happy I found it.

This plug-in is useful, and hopefully will support running only when the download file is larger than 1mb

Works like a charm!
A minor UI suggestion: it could hide the long, long urls of the download from the popup tab, and add a "tap-to-expand" button in case a user wants to examine the full urls.
Thank you for creating such a great addon!
