Created attachment 764646 [details] Before and After User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.44 Safari/537.36 Steps to reproduce: I have installed several addons that add drop-down options to the Message Send button or as a stand-alone butto in the main toolbar. In particular SMTPSwitch and SMTPSelect. They are supposed to add a drop-down list of the configured SMTP servers, allowing to select which server to use (becomes default until further selection). Actual results: Until beta 21 everything ok. From beta 22, the list doesn't show, meaning that no option drops (it's not an empty list, nothing happens at all. There is just a small square showing immediateli under/left the Send button. Expected results: A usual drop-down list should appear.
Have you contacted the extension author? Also is there anything in tools->error console after the dropdown fails?
Summary: Drop-down menu items not showing → With "SMTPSwitch" and "SMTP" addons, clicking Send button's drop-down menu part does not show/popup the dropdown
As a workaround, I installed SMTPSelect 1.2.1 on TB 23 and it works.

But you still can contact any of them so they can tell us what they think changed in Thunderbird.
