So, the extension for Firefox that allows users to drag and drop attachments onto emails seems to have a hard-coded limitation to Firefox versions <= 3.05
There was an earlier workaround that involved editing the maxVersion parameter in the XPI file that held the DnD extension.
The workaround does not seem to work anymore--I think the XPI is now signed, and can't be tampered with.
Meanwhile my users are really missing that DnD functionality for their attachments!
Any news on an update to the Zimbra DnD XPI for Forefox 3.06 and above?
