Everyone - there have been a few reports about folders not being shown in Mozilla with the latest Binc (1.2.1).
I have created blank test accounts, cleared out all binc state files and logged in, only to see that the folders are detected as expected when chosing "subscribe".
So I can't reproduce this problem. If anyone can help provide more detailed information about the problem and how to reproduce it, then I'm sure we can solve it.
Ok, I'm now 100% sure this is a Mozilla bug, specifically Bug#136749. It's also not that critical because merely collapsing and re-expanding the hierarchy makes the subfolders show up again (at least in recent Mozillas).
However, for completeness here's how to reliably reproduce it...
Manually create a fresh folder hierarchy, as follows
mkdir Maildir; cd Maildir
for i in A B C A B.a B.b B.c C.a C.b C.c C.c.1 C.c.2 C.c.3; do
mkdir $i $i/new $i/cur $i/tmp
doneStart Bincimap
Start a fresh instance of Mozilla or Thunderbird, with no existing configuration for this mail server. Configure an account for it.
Log in. You should see INBOX and nothing else.
Right-click on INBOX and choose "Subscribe".
You should see INBOX, unexpanded. You can now expand it all the way down the entire hierarchy... so far so good!!!
Click the "Refresh" button. Boom. A, B, and C now no longer have subfolders. Collapsing and re-expanding the hierarchy deterministically makes the subfolders show up again, so it's not that critical, merely annoying.
