Why Am I again having downloads abort after another firefox update
The error message is an unknown error has occurred please try again. The files are often left as bit parts depending on what download service they are from. I should not have to disable real time scanning because of this problem. Real Time scanning is one of the necessities of anti virus protection and downloads using firefox should work with my anti virus real time protection and not abort. I reverted back to the download box which got replaced in an upgrade of firefox a few months back because of this problem and it is now prevalent again.

I'm also using Firefox v24 with the new download UI and real time scanning and am not having this issue.
As a first step I suggest you try the suggestions in the following article:
Do any of these work?
If not please try booting Firefox into Safe Mode and testing again. Does the problem still occur in Safe Mode?
If the problem does not occur in safe mode then most likely one of your add-ons or a setting is causing the problem. Follow the instructions in the article above to troubleshoot and identify the culprit.
If the problem still occurs in safe mode then I suggest doing a Firefox Reset. This will return Firefox to its default settings. Your personal data (bookmarks etc) will be saved but you will need to reinstall your add-ons.
I hope this helps. Let me know if not.
It usually depends on whether your security software waits for Firefox to finish the download and pass control to have your anti-virus scan the file or that your anti-virus software already starts scanning while Firefox is still downloading. Firefox closes the file after saving each chunk and that can make your AV software think that the download has already finished.
Thank you Cor-el ! This is what is happening but it has only started happening again since the upgrade to Firefox 24. I am downloading with the Mcafee real time scanner turned off at the moment to see if the downloads complete. I will post if I am successful. The problem is intermittent when the Real-Time scanner is on as I did manage to download a file last night with it on. A Mcafee update downloaded earlier and about 5-10 minutes after my downloads aborted with the message the Source file could not be read. Is there anything that can be done to rectify this problem? Is it Mcafee or Firefox?
I can confirm that this problem is intermittent. The files abort at the very last few seconds of the download sometimes, a bit part is left over or there is nothing. When I turn off McAfee real time scanner the files complete. This has only been happening since the Firefox 24 upgrade but I have had this problem before after other Firefox upgrades. The error message is an unexpected error occurred.
What can be done to fix this problem?
