Downthemall is not available in the download popup window


I used downthemall (DTA) in the earlier version of firefox and it was doing very well. Whenever I clicked on a download link a popup window appeared with the four options; a) run, b) save file, c) save with dta one click and, d) save with downthemall.

But now, Only two options (a & b) appear and I am not able to download with DTA anymore like the old times.

Is there something which I am not doing correct and I need to know something? Please help.

Please contact the developer for support. Keep in mind that extensions are more limited in what they can do compared to years ago.
