Comment 5 for bug 406512

Same problem here: I have FF 3.6.3. opened on Lucid and I'm logged in to RTM, but "pressing the Authorize button in config dialog" (when running gnome-do -debug from terminal) only yields:

[Error 10:24:11.681] [RTM] Not authorized to use a Remember The Milk account.
[Error 10:24:11.780] [RTM] Failed to initialize authentication.
[Error 10:24:15.360] [RTM] Failed to complete authentication.
[Error 10:24:17.404] [RTM] Failed to initialize authentication.
[Error 10:24:20.945] [RTM] Not authorized to use a Remember The Milk account.
[Error 10:24:20.949] [RTM] Not authorized to use a Remember The Milk account.
[Error 10:24:20.952] [RTM] Not authorized to use a Remember The Milk account.

No further info is given.

I'm behind a proxy, so maybe that could give some problems? Though I did an 'export http://proxy.server.com:8080/' in my terminal.
