I use to be able to download vevo video's from youtube. I would see the download helper give me the details of how much time is left in the download. All of a sudden it just downloads 0% and when coverting to hard drive it gives me a error.
Download Helper has been fixed.
New release 4.9.10 today !
It automatically notified me.
One glitch though, there was no link from the notification page for the update.
Had to do it thru Mozilla and search for it.
But it does work now as good as before.
I had Video Download Helper v. 4.9.9 and I was able to update to v. 4.9.10 from the Firefox Add-ons -> Extensions panel by clicking on the "Gear" box (top right) and selecting "Check for updates". Firefox then found the available update and I was able to install it directly from the Add-ons Manager.
