How can I know which directory corresponds to which firefox extension?

Question

In my firefox's extensions folder (~/.mozilla/firefox/PROFILECODE.default/extensions, I have a list of folders and .xpi files most of which have unintelligible names:

While some of these are named in a way that is informative ([email protected] for example), others simply have a hex string as a name. Is there a way for me to map these to the corresponding extension's human-readable name?

I'm using firefox 30 on a 64bit Debian.

Click on Help | Troubleshooting Information (if you don't see the menus, you can show them by clicking on the 3-bar symbol on the right, click Customize in the lower left of the window, and the Show/Hide toolbars option will be in the lower left of the Firefox window).

This will open a window with a lot of information on things like internal settings. Near the top is a section called Extensions. The ID field on the right has that information.
