The Outer frame was present, there were just no tabs. System is recently installed from RedHat 9.0 (1.2.1) twice upgraded using your RedHat8 RPMs. This problem only arose in the 1.3 to 1.4 upgrade. Opening new windows and showing/hiding the sidebar did nothing. Customizing the sidebar came up empty as well. (My normal entry path is through Mozilla Mail first.) Completely closing and restarting Mozilla brought the sidebar tabs back. The only other thing that happened was that on the first launch after the upgrade, opening a new window displayed one of the RedHat local pages and not the default (Mozilla.org/.../start) home page. I poked about and found the following bugs. All of which seem old.

To the point of hiding my personal toolbar and the disappearence caused a brief start. Hopefully, this will help anyone else who stumbles on this. Thanks, David Reproducible: Didn't try Steps to Reproduce: 1. 2. 3. Actual Results: Sidebar panel contained no tabs after upgrade. Expected Results: Shown sidebar tabs.

always reproducable for me, no matter of which version were talking about, that is 1.3 and later. doesn't matter if I install a release or a nightly, the sidebar is always blank anyways. Noticing also that the "Tabs" meny on the sidebar is empty, although there are tabs in the sidebar, both on first start and later ones.

ditto going from 1.4 to 1.5a on Windows 2000. On first start sidebar had no panels but in all other respects seemed OK. Just restarted Mozilla and the panels came back no problem.

This sounds like bug 195213, any change with newer builds? I seem to recall having this problem myself.
