Linux Mint Cinnamon 17.1
Firefox 36.0.1
DownloadHelper 4.9.24

I often download video tutorials on various subjects so that I don't have to re-find them when I want to go back over things. Download Helper has worked great for this, until it just stopped downloading. It still spins it's little balls to let me know what I am playing live is downloadable, and it still lets me tell it what I want the file named and were to store it, and when I tell it to save the file, it still adds the file to it's count of what it is to download, but the progress bar at the bottom never registers the file, and it never shows up where I told it to deposit the finished file.

I have a second computer that is running the same linux, same firefox, and the same Download helper, and without a problem.

I tried re-installing Download Helper. Nope!

I tried re-installing Firefox. Nope!

I tried disabling all of the extensions in Firefox except Download Helper. That didn't work.

I tried creating a new temporary profile for Firefox and installing only Download Helper after I launched Firefox. That didn't work either.

I finally re-installed Linux Mint Cinnamon from scratch, and tried Download Helper in Firefox before I added my customizations to the Linux, but that didn't change the situation either!

Any ideas as to what I should try next??? Thanks!

Try starting Firefox from the command line, then using downloadhelper for something.

There's a chance that download helper might throw a useful error message to the terminal. I'm not really optimistic, but it can't hurt and might help.

Here is what Terminal Reported:

I've been looking at that readout, but have no idea what firefox is tellin me about what is going wrong...

Currently, Download Helper only works up to Firefox 35.

Shortly after posting this, an update for 5.0.1 came out, and now works with at least Firefox 36.

Thanks replica9000!

I had actually found the new update, 5.0.1, and noted this in a post to this thread when I marked it SOLVED, but I don't see my entry here, so it must not have posted. Maybe one can't both post and marked solved at the same time...or I did something else wrong.

But, my Download Helper is happy again! Thanks for all the help!

Glad you got it working.
