Registry Viewer (SeaMonkey below v2, Mozilla, Thunderbird below v1.5, Firefox below v1.5)

Mozilla and its derivates use a special database format inherited from older Netscape versions, e.g. for their version registry mozver.dat or the profile registry registry.dat. The Registry Viewer (Tools → Registry Viewer) provides a nice, handy tree view of the contents of these files.
