I'm using Mozilla Thunderbird 9.0.1 with Lightning 1.1.1. Is there an easier way to import an ICS file attached to an email than saving it to disk, then in Calendar going to File –> Open?
If I select "Open with Thunderbird" from the save dialog, it just opens a new mail message and attaches the file to it.
(I did see this older question, but it refers to much older versions of Thunderbird and Lightning)
Update: I've updated to 10.0 and 1.2, respectively and it still doesn't work right.
Update 2: Bugzilla.
