After a recent update to the latest version of Lightroom my Flickr module was no longer set up. When I go through the steps and try to authorize Lightroom to access my Flickr account, I get this message:
"File not found
Firefox can't find the file at lightroom://com.adobe.lightroom.export.flickr/#?oauth_token=72157648892999080-2b7a3de0c71 f2979&oauth_verifier=2a97b5ba5b2a7886.
Check the file name for capitalization or other typing errors.
Check to see if the file was moved, renamed or deleted."
