Right now, themes try to make the name picker look like a textbox. Instead, an actual textbox element should be used.
spin-off from bug 433055
Bug 451915 - move Firefox/Places bugs to Firefox/Bookmarks and History. Remove all bugspam from this move by filtering for the string "places-to-b-and-h".
In Thunderbird 3.0b, you do that as follows:
Tools | Message Filters
Make sure the correct account is selected. Click "New"
Conditions: Body contains places-to-b-and-h
Change the action to "Delete Message".
Select "Manually Run" from the dropdown at the top.
Select the filter in the list, make sure "Inbox" is selected at the bottom, and click "Run Now". This should delete all the bugspam. You can then delete the filter.
it is a common textbox now!
