In preferences.xul I see this comment: <!-- commented out until bug 82487 is fixed <treeitem id="offlineItem" label="&offline.label;" helpTopic="mail_prefs_offline" url="chrome://communicator/content/pref/pref-offline.xul"/> --> However bug 82487 is long since fixed. Meanwhile the UI for this pref has moved to Mail&Newsgroups -> Offline&Disk Space. To quote Bug 221734 comment 19: > - pref-offline.xul was created by me in bug 221736 to move some mailnews prefs > to the mailnews section where they belong. > - The offline startup prefs were left in place, since they are not mailnews > specific. > - The offline startup prefs were commented out pending the fix for bug 82487. > They still are where they have always been, so that we now have a duplication > of the prefs. I propose to remove the communicator pref-offline UI since: 1. It's the old XPFE <panel> so would need to be totally rewritten anyway. 2. Commented out since 2001 and nobody noticed in the intervening 9 years, or at least enough to care. 3. There is functional UI in the prefwindow that deals with this pref anyway.

Proposed patch.
