E10 Multiprocess, Closed Private Windows Produce, "File Access Error".

[teddyrogers]

Your DownThemAll! and Browser Version and Operating System

DownThemAll v3.0.5
Firefox v48.0.2 (Multiprocess Windows - 2/2 (Enabled by user))
Windows 10.1607

** Note, multiprocess has been manually activated in Firefox. **

Expected Behavior

Files download and finish without ending with error message, "file access error".

Downloaded files can be located in the download folder.

Actual Behavior

With multiprocess (E10's) activated and whilst using private windows, files download and finish with error message, "file access error", in DownThemAll. Note, private windows must all be closed whilst downloads are still in progress for the error message to appear before the downloads reach 100%. See steps to reproduce below. DownThemAll works fine otherwise.

Files cannot be located in either the temporary or download folders. I am assuming they get deleted in some way.

Steps To Reproduce

0. With E10's activated (Multiprocess Windows - 2/2 (Enabled by user)
1. Open a private window.
2. Go to a website and start downloading files.
3. Close private windows ** this must be done whilst downloads are still being downloaded! **
4. DownThemAll continues to download the files until 100% finished.
5. DownThemAll displays, "file access error".
6. Files cannot be found in either the temp or download folders.

Files can be resumed which restarts downloading the files from the beginning again. Files will complete 100% successfully without any problems.

Got a Diagnostic Log?

Thank you for the reply. I think my "bug" may not be exactly the bug as I described after more testing. When I enabled logging the problem seemed to go away, though I am not sure how accurate that statement is. I also noticed that the bug may actually be related to the one just reported...

I have however noticed other odd behaviour with archives being corrupted after downloading. It usually seems to happen when I close all the private windows and have a number of files downloading at the same time. All I know for sure is something weird is happening!
