I use “1-click Youtube Download”. It works. I have “download Helper”, but I think that YT has redone some things, again.

I can click on the videos on the side and play them, but when i wish to down load them, it shows the LAST one downloaded, and will re-download that, but not what is presently playing.

Yes, it is frustrating.

I’m running FF 25.0 and downloading MP4’s and FLV’s works for me.

Try re-installing the YT DL extension and/or upgrading to the latest version of FF
