The problem is "fixed" if you check/uncheck the tabs-on-top option twice. This
looks like a regression from bug 571992.

duplicate from ?
(although your issue is different, this is a regression from so they are most likely caused by the same patch).

Tabs moved to bottom after going after previewing a persona

I filed it because this was personas, I almost commented on the other bug.. but just wanted to make sure I guess if the underlining code was different, to have it separate.

This is what I see after bug 513162 landed after the switch to tab bug.

Note I didn't apply a persona, I just previewed it.
probably another -moz-box-ordinal-group bug

Summary: Tabs-on-top change to tabs-on-bottom if going from default theme to persona → changing system theme/screen resolution and/or previewing personas causes tabs-on-top to switch to tabs-on-bottom

I guess this also happens when switching personas in the addon manager if you have tabs on top, it goes to the bottom.

System theme changes between Aero themes and non-Aero themes with having tabs on top setup properly, will cause tabs on top to switch.  

However, it does not occur changing from one system Aero theme to another.
This seems to be Aero theme only.  I can not reproduce this under Windows/XP.
Dao, patch incoming?

Oh, this is deeper than just CSS styling, it's something in the core. CC'ing some relevant folks who might be able to help.

This is a pretty visible bug on trunk these days, and blocking the first beta.
Should the discussion of the core bug stay in bug 555987, or is this somehow different?  (Does one of the Neils know the relevant bits of nsBoxFrame?)
If this is the same, it can happen in bug 555987, I suppose. Do we expect the fix there will resolve this one, as well?

This worksforme on Linux.  Is this Windows-only?

It is, yes.
The patch in bug 555987 fixes this.
