Firefox and opening attachments

I have been using firefox for some time and have been trying to open jpeg files with windows fax and picture viewer. I have been unable to find that utility with the browse feature.
We have adobe and Kodak software on this PC and the settings are set for all jpeg type files be opened with the windows and fax viewer, however firefox dose not do it. The new updates list many more options for opening jpeg files but the one I want isn’t there??
Could anyone help me?
