"!!! [dwhelper] init: [Exception... "Component returned failure code: 0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE) [nsIJSCID.getService]"  nsresult: "0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE)"  location: "JS frame :: chrome://dwhelper/content/dwhelper.js :: <TOP_LEVEL> :: line 9"  data: no]"

... for every window Firefox opens. Why? Firefox 3.6.13.

I solved this one today on a Mac. The problem appeared when I was copying the profile from one user A to another user B on the same machine. In that profile folder were three files and one subfolder named 'extensions'-something that seems to contain a folder for any extension user A installed.

After the following procedure I had to reinstall all extensions, but mirically all setting were there. In (for) any case remember to have a backup of your data. Here is what I did:

Stop Firefox; rename Profile to Profile-old; Start Firefox; Stop Firefox - now you got a new clean Profile folder - copy the extension folder and the three extension files from the new Profile to Profile-old; delete Profile; rename Profile-old to Profile; start Firefox; reinstall extension; done
