The extensions will not appear in the add-on Manager; Error of Java to start Firefox

When I click on tools-> addons, modules Manager opens but no show extension in the "Extensions" tab.

I think that the problem is related to a start-up error message I receive. Whenever I open Firefox, an error message titled '[JavaScript Application]' opens and displays the following text:

Any help would be appreciated.

I had the same problem.
(1) to fix it, you can check what addon is responsible for this mistake by viewing the extensions.log file in you profile file (lines).
(2) access to the extensions of subfolder in your profile folder and delete appropriate addon xpi file or folder addon if it is not packed in xpi file.

But ideally Firefox should protect Manager addon is better error in Addons (same addon disabled may cause this error).
