I currently have Firefox 14.0.1 installed and working properly. According to my control panel, Firefox 5.0, 6.0.1, and 13.0 are still installed, or on the programs list anyway. How do I get rid of them? I can't seem to locate the folder it says they're in, and they won't disappear from the programs list.

That are likely only leftover (orphaned) registry entries that weren't removed by the updater and the Firefox version that they refer to are no longer present.
Easiest is to use the registry editor to remove those entries yourself manually.
