Why are long downloads ending prematurely?

I just tried twice to download OpenOffice 3.4 on a dial-up connection. The file is supposed to be 145MB (only practical as an overnight download, to be sure). The first time, it stopped at 655KB. The second time, I tried it from a different mirror site. This time it stopped at 29.3MB. Both times it had said the download would be 145MB, yet both times it appeared to think the download had completed far short of that. What the heck is happening?

It is possible that your anti-virus software is corrupting the downloaded files or 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.

Sorry for my delay in replying. I tried it with antivirus real-time protection turned off, and got only about 46MB of it. I tried again, this time in Internet Explorer, and got the whole thing.

I rarely had any trouble downloading big files in FF 3.6; when I did, it was usually a problem at the source. What has changed?

please try updating to firefox 13 and see if the issue is persisting. if so, please also try launching firefox in safemode once to see if you can reproduce the problem there...

A couple of nights ago I tried downloading a 69.7MB Java update from Oracle. I've upgraded to Firefox 13 and tried it with antivirus real-time protection turned on. The whole thing came through. Then I decided to upgrade Java to version 7 instead of just patching version 6. I downloaded the 87.9MB update to do that, and again got the whole file.

It's looking like there's a bug in Firefox 12's download engine that's been fixed in version 13. I may try it with a bigger file to make sure.
