Doesn't look centered to me. Win7 Pro x64, Minefield nightly build 20100324040325.

I guess it doesn't show up with the windows classic theme then.

Default theme, same version of Minefield, same OS. Removed the StumbleUpon toolbar and the Personal Toolbar. Still not centered.

The directory I was using to test builds must have had some residual files that don't get overwritten when unzipping causing the difference, because after clearing that directory and trying the same build I can now reproduce. Sorry for the confusion.

Regressed between 100316 and 100317. I believe it's a regression from the fix on bug 347930.

with this fix when tab bar doesn't overflow you can not drop tab all the way to the left.

when ever we drag over the 3px margin the drag indicator disappear

if you bring back -moz-padding-start: 3px;

then you can fix the drag indicator position by (this is for left to right):
add
+ var ibRect = ind.parentNode.getBoundingClientRect();


replace
var minMargin = scrollRect.left - rect.left;
with
var minMargin = scrollRect.left - rect.left - ibRect.left;

replace twice
newMargin = tabRect.right - rect.left;
with
newMargin = tabRect.right - rect.left - ibRect.left;;
