I'm running Firefox 12.0 with DownThemAll! 2.0.13 on Vista Business x64. Recently everything that DTA downloads is corrupted. Error message when trying to execute:

[Window Title]
C:\Users\me\Downloads\file.exe

[Content]
C:\Users\me\Downloads\file.exe is not a valid Win32 application.


[OK]

When I download with Firefox's built-in manager they work fine. I tried resetting DTA's settings to default but that didn't help. Has anyone else run into this?

Update: submitted bug to DownThemAll.

It does indeed seem that others have run into this bugs.downthemall.net/report/1 as reported by the number of bugs involving incomplete downloads, corrupt downloads, the occasional inability to get the correct file size, etc. –  Bon Gart May 4 '12 at 19:01

That means it's a corrupt download. Download managers are prone to many data corruption issues in cases with inconsistent data connectivity, and it takes a lot of work to make it work the way it's supposed to.

If DownThemAll has a "rollback" option, you should enable it. That means that when a thread is paused or loses connectivity or stalls for whatever reason, instead of continuing where it left off it should rollback a small amount (usually ~4KiB) and start from there. None of this, of course, is actually required if the code properly handles all scenarios and doesn't have any off-by-one bugs, for instance.

I tried setting it to 4KB but there was no change, thanks though. –  travis May 4 '12 at 21:18

After enabling logging in the DTA extension, and going through the logs, there were error messages generated by YSlow. After disabling YSlow and restarting Firefox everything works beautifully again.
