New Mail Window should not use so much rows for recipient

[klumy]

Currently it use up to 3 rows for the the recipients. this reduce the effective area usage on small monitor resolutions. can this be fixed in new version?

You can do that yourself with a modification of the "mail.compose.addresswidget.numRowsShownDefault" preference. The default value is "3".

Use Options > Advanced > General Tab.
Click the Config Editor button.
Dismiss the warning.
Search for the preference. I used "compose" (without quotes).
Select it then right-click and click Modify.
Enter 1, Click "OK".
Close about:config and you are done.

Many thanks
very strange that this can not be accessed via normal menu. only via about:config

Well, it is a user interface configuration change, not something often needing change for sending or receiving mail.
