so my wife's thunderbird just got updated, security fixes you see... besides suddenly having all new fonts and sizes, the left pane got rearranged without her permission. at the top is a set of phantom folders, inbox drafts templates sent, all empty, followed by her actual archive. then below the archive (which is extensive) is junk which is accumulating junk from her single gmail account, then comes her gmail account which by rights should be up at the top where she is used to it. bear in mind she is very sensitive to people changing her settings without her approval, she just moved from samsung phones to iphones over this. how can I fix this? I am tempted to bare metal revert versions but that won't fix the security vulnerabilities. this reminds me of a transporter incident, somehow an attempt was made to make a 'unified folder' system when there was in fact only one account, now it is all a hodgepodge.

HELP!
