This is a version of XPCOMViewer with Komodo installation enabled.
This extension is handy for browsing XPCOM interfaces available in XUL applications, such as Komodo. See http://xpcomviewer.mozdev.org/ for more details on XPCOMViewer. The version on the Mozilla Addons site has disabled all XUL applications other than Firefox.
You really suprised me because even I did the XPCOMViewer I didn't know that you post it here.
And here one note: the reason why are other XUL applications disabled in the Mozilla Addons site is simple - when I tried to upload XPI package it cann't be finished because they have some parser which check the install.rdf file for supported applications and Komodo wasn't supported.
By the way - thanks for spreading XPCOMViewer ;).
I grabbed the latest version off of the addons site and it's working fine with K6.
