More info - I think it has to do with permissions (whatever this is), because I played around with profile restore and I think the permissions are influencing this.

What is the default download location?

Do you have write permissions for that folder?

Did you try another download folder?

Also make sure that Anti-virus software isn't preventing write access to the files in that folder.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

See "Disable virus scanning in Firefox preferences - Windows"

Cor-el, thanks for replying. My default locations is "downloads", and I have Windows write permissions for it, as well as the rest of my drive. I am the admin on my PC. I tried other folders. my antivirus is not the problem - I've tried disabling it and no go. When I mentioned "permissions", I did not mean Windows, but Firefox. I mentioned these because I played around with FEBE (the addon) and it seems that restoring "permissions" from my profile to the test profile I was working with "restored" the error.

updated to Firefox 6 - didn't help deleted "permissions.sqlite" - didn't help

Please help

You can check the file attributes of all the files in the Firefox Profile Folder to make sure that you have write permission.

Create a new profile as a test to check if your current profile is causing the problems.

See Basic Troubleshooting: Make a new profile:

• https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

another piece of info - the problem seems to often "skip" files smaller than ~150MB.
