Summary: Both "Ctrl+Tab" and "Ctrl+Shift+Tab" can't move tab again; → Both "Ctrl+Tab" and "Ctrl+Shift+Tab" can't move tab again [@ PageInfo]
However, if you go to a https: page, then Ctrl+Tab and Ctrl+Shift+Tab does work
on the Security tab in Page Info.  It looks like there must be some focusable
content on the tab, or the keys won't work.
I should probably finish fixing bug 175893 which fixes a bunch of problems with

Don't have the time right now -- anyone else want to take it?
Depends on: 175893
I'll take it. Seems the problem is in the security page, not the tab.

FYI, Mozilla tab controls currently expect focusable child content, becuase they
try to advance the focus into the content when you flip tabs. Unfortunately
although named advanceFocusIntoSubtree the function used can actually advance
focus right out of the tab control...
Aaron's (bitrotted) patch resolves the problem by setting tabs to flip even when
they are not focused (like Ctrl+Tab in the browser).
Neil, thanks. my comment 4 was wrong. there is a hidden-disabled button in 
the "Security" page, it blocks the Ctrl-tab.
I think this bug and bug 130644 should be merged into 1 single bug. Summary,
