I posted this in the Thunderbird support forum, but haven't received a reply, and have an event with 200 people coming up in two days without access to my emails, so I hope no one's offended by the crosspost.
Portable Thunderbird OSX meltdown
I am running Portable Thunderbird on a USB drive on OSX. Today it just crashed completely - got stuck opening a message. When I restarted, all my folders were gone, everything moves at a snail's pace, but my settings remained.

Copying over the entire app to the hard drive. Error message "some content in the inbox is incomplete".
Deleting the msf files. Couldn't do the next step, rebuilding the index files, because there was no right-click option for that on mac.
The USB is not out of space, 4 Gb left.
Thanks in advance,
