Thunderbird: форум сообщества

When I Reply the cursor used to default to the text so I could just start typing my message.

Now it defaults to the address field. How can I go into the hidden settings to change it?

On my new T-bird installation, I cannot find a way to add Send-Receive as a customization of the toolbar area, nor do I find so far any other way to send-receive, aside from interval-based automatic sending and receiving, and of course composing and sending a new email. Em-client has an easily accessed send-receive button, as does my long-time Outlook desktop client.
