"Firefox could not install the file at

http://releases.mozilla.org/pub/mozilla.org/addons/10868/firefox_sync-1.6.1-fx+fn+sm.xpi

because: Invalid file hash (possible download corruption) -261"

I did have 3rd party cookies enabled. Today the update succeeded without error (after about the 10th try).
