Thank you very much for fixing the Browser Console links. I was starting to miss that functionality.
Your attached extensions have the error that I reported here
(Copying button URI to clipboard breaks DOMParser constructor globally). You can test it by simply copying any button to the clipboard from the button context menu and then reinitialize you Extensions Developer Tools button. You will see that it doesn't reinitialize. Just to be clear, the DOMParser breakage happens only on latest versions of Firefox. It doesn't happen on SeaMonkey, for example.
I would really like for you to fix this error on the signed and not signed versions so I can attach your extensions in the very first post of this topic.
