It never did fully, (always left "dconf") but now it leaves:
/home/[username]/.cache/mozilla/firefox/[profile name]/{cache data}, and
/home/[username]/.cache/thunderbird/[profile name]/{cache data} !
Also FWIW, BB never did delete:
/home/[username]/.adobe/Flash_Player/AssetCache,
and it leaves an "InstallTime..." file in
/home/[username]/.thunderbird/Crash Reports
