My downloads will not open when I double click or right click in the download manager. What is going on?
I cannot open my download by right clicking and opening, or by double clicking in the download manager. I have windows 7. What is the problem? I do not have a problem with internet explorer with the same download.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.
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"
