When I download files in Firefox they only get about 99% complete even though it tells me they downloaded successfully.
9 out of 10 times my download gets truncated in Firefox. For example, let's say I was downloading a 42.2 mB file, it would get to about 42.18 and then complete. I would then try to open the file to find it was corrupt. I would then open up IE9 and download the exact same file, and I would get the full 42.2 mB and the file would open flawlessly. I have tried disabling all extensions/addons, nothing. I have reinstalled Firefox cleanly a few times, no dice. I have tried disabling any file system protections I have, nada. I'm at a loss right now as to what else I can try. I love Firefox, I've been using it since it's original release, but I need to be able to download. Every other browser I've tried works great in that department, except for Firefox all of a sudden. Anyone have an idea?

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Reset Firefox – easily fix most problems article.

Just tried that, but the issue persists. Any other ideas?
Does anyone have any idea what could be the cause?
It is possible that anti-virus software is corrupting downloaded files or is otherwise interfering with downloading files.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
I have tried disabling all filesystem protections I have, didn't work. Also tried everything listed in that article already, still the same problem.
