Nice extension, unfortunatelly "From" is somehow shifted 15px upper than it should be. In source CSS there is something promissing it will be ok, but it is not.

I worked around it by putting:
#expandedHeaders {
margin-top: 15px !important;
}
into userChrome.css.

Or even better, if you have more buttons with labels and if you don't mind one more line:
#expandedHeaders {
margin-top: 37px !important;
}
#header-view-toolbox {
margin-left: -2000px !important;
}
so important "from" field will not be hidden behind buttons. (It is generally silly that TB3 devs put all buttons on the same "line" as "from" filed....)
