I have a similar error message while trying to upgrade the Web Developer extension. My current version is 1.1.5, and its updateURL is: <em:updateURL></em:updateURL>

The url to download the latest version at that url is:

At the moment, this url returns a 302 with a new location at:

This one also returns a 302, with another location:

Now, putting some breakpoints on all the possible spots where this DOWNLOAD_ERROR can be triggered, on my case, at least, I ended up with this stacktrace:
#0  nsXPInstallManager::OnStopRequest (this=0x7fffd8cc8060, request=0x0, ctxt=0x7ffff7ede040, status=3) at nsXPInstallManager.cpp:1209

status=3 is not specifically handled by nsXPInstallManager::OnStopRequest, and is NS_BINDING_REDIRECTED according to netwerk/base/public/nsNetError.h, which means, (again) at least in my case, the download error seems to be due to the multiple redirections.

Obviously, installing the file from disk after downloading it by hand, works.

Please tell me if I shall report a new bug for my issue.

I have the same for the plugin's and tried with different ones: Adblock Plus and ReminderFox.

Firefox could not install the file at
because: Download error

Firefox version v3.5.7

Location: Australia

I guess it could be a mirror issue, I get an empty Http page delivered when hitting this address. My home computer the same.

I was not able to replicate this bug using Nightly 16.0a1 (2012-06-14) and Windows 7(x86_64).  The stated add-ons (CookieSafe, Adblock plus, and ReminderFox) download and install without issue.
I downloaded these add-ons (CookieSafe, Adblock plus, and ReminderFox) and they download and install without issue and nothing wrong, working Ok..! using Nightly 16.0a1 (2012-06-15) and Windows 7(x86_64) the same thing as Ross.
These problems are temporary for the most part, so it is best that you post them to the AMO Forum: Us admins can take care of them fairly quickly.

If there are any of you currently experiencing any such problems, I'll be happy to look into them.
