Description of problem:
I can't see an entry in Firefox' general extensions list.

Version-Release number of selected component (if applicable):
mozplugger-1.14.2-1.fc14.x86_64
firefox-3.6.13-1.fc14.x86_64

How reproducible:
always

Steps to Reproduce:
1. run Firefox in safe-mode and check "disable all extensions"
2. try to enable extension again (how?)
3.
  
Actual results:
PDF for example opens again in a new window of epdfview. Mozplugger can not be chosen any more as application handler for mime types.

Expected results:
mozplugger works just as expected ;)

Additional info:
User should be able to handle mozplugger like any other extension, e.g. AdBlockPlus or NoScript - both available also as official Fedora packages.
