Amount downloaded exceeds total size of file?
I'm trying to download a few files from one certain site. None complete because once the size of the file downloaded matches the file's actual size, both 'download speed' and 'est. time remaining' turn to 'unknown' while the amount downloaded doesn't stop; eg 4.0 MB of 3.0 MB completed. Is this the site's problem, and not an issue with Firefox? All downloads from other sites run normally.

Hard to say what the problem might be caused by. Could be that one download server, or it might be the FireDownload addon that you are using. Or it could be Firefox itself.
Do you have that problem with that particular download server with Firefox running in the Firefox SafeMode, or with that addon disabled? http://support.mozilla.com/en-US/kb/Safe+Mode
Or you ask about that problem at the support pages for that FireDownload addon. http://www.fireaddons.com/support/
