Update the TorBirdy AMO page to reflect its state and requirement
Please think about updating the AMO page of TorBirdy to include that this addon is still experimental.
I think it would be good to add the information that it requires Tor to be present (and running). (TorBirdy does not work on its own.) (People seem to have expected this from TorButton).
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
