Steps to reproduce:

Firefox Nightly. Open a new window and pause for a few seconds until the title/tab bar shows "Nightly" in the center. Open a few new tabs until the overlap the "Nightly" text. 

"Nightly" text appears under the tab and is obscured under the tab text.

Next, type a web address in one of the new tabs. The pages title replaces "Nightly", and depending on length, is obscured by many tabs. This can be repeated for any new tabs and the title will update when switching between those tabs.




Actual results:

Pages title are displayed behind the tab bar and the transparent tabs overlap with that text.

I am using the "default" nightly theme which seems to have a black background and black text with a drop-shadow for tabs and the title. When I was taking screen shots for this bug you'll notice the tabs appear to be light gray. I then switched over to the light theme and the issue was still occurring but the screenshots show the color accurately.

I added a yellow background to the png output to show the transparency.


Expected results:

The page title should not appear behind the tabs. And maybe screenshots should show the same thing I see on the screen
