We have a common complaint among (former) Netscape 6 users. People who uninstall Netscape 6 are no longer able to open jpegs and other image files. Windows complains that it doesn't know what application to use to "Mozilla jpeg". The reason for this is that builds of mozilla created before Feb 7, 2001 including Netscape 6 do not properly restore file associations to the state they were in before the browser was installed. Use this uninstaller to restore these file associations. See bug 64727 for more info. http://bugzilla.mozilla.org/show_bug.cgi?id=64727
