That happened with mine after several months of trouble free use.  It's
been awhile since that happened and it hasn't happened again, and I
don't know why it happened.  But I fixed it by creating a new folder,
copying all the messages in the inbox to the new folder (I think I
called it inbox2) and then I think I actually deleted the inbox.  Not
sure about that, but I think I did.  If Mozilla won't let you do that,
just copy the messages back into the empy inbox.  I think what happened
is that I did delete the inbox, and then closed Mozilla and started it
again.  It created a new inbox, and I've had no trouble since then.
Good luck!  Bill Kendall
