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

Excelente para descargar videos.

Quite useful. But it desperately need an option to remember temporarily. Like another checkbox inside the one that already exists to instead of remembering forever, remember for X minutes or remember for the current tab and domain.

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.

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!
