Ash sent me a few screenshots a week or two ago that show that the top line of the headline is not aligned with the top border of the icon to the left. I tried fixing that but wasn't very successful, there seems to be a "padding" that the font rendering creates and as that's flexible depending on the font and size I wouldn't know how to fix this properly.

Ash, can you attach the screenshots showing this misalignment in the Control Center?

I think I figured this out. It looks like the logo is currently just a *touch* too high (as you can see in this screenshot where i've replaced the background image of the section with gradients and drawn a line across the TP section

Same thing, but with my patch applied
I realized that my patch makes the header container top-aligned with the image, but the text still doesn't have a sharp top alignment with the image. Is this what we want? (see attached screenshot) Note that if we want the top of the text to align with the top of the image, it won't always happen in the case where all of the text is lower cased (like about:preferences)

I guess qe-verify+ but it's going to be very subtle.

Its ok if that breaks when its all lower-case or has no ascenders. https://www.dropbox.com/s/fr3vh38zzpuhjgc/Screenshot%202015-08-11%2015.11.21.png?dl=0

Looked further into it, it appears that there is some line-height that is set when <label value="foo" /> is used that isn't accessible via CSS on the label selector. But if you do <label>foo</label> you can set line-height: 1 which aligns it properly. Unfortunately I'm not sure if it'll be practical to switch to this, since setting it to use textContent doesn't seem to crop long strings correctly.
So I spent some time debugging inside nsTextBoxFrame (which is the frame used when setting value="" as opposed to textContent). As best as I can tell, I think GetTextSize [0] is somehow not taking into account the line height of the element. I'm going to upload a patch that makes things better across systems by just tweaking the existing padding / margin, but I think it's not going to be possible to get this pixel-perfect across all default fonts unless if we come up with a fix in the XUL layout. I don't think it's worth spending more time on this, though. [0]: https://dxr.mozilla.org/mozilla-central/source/layout/xul/nsTextBoxFrame.cpp?#1017
With the default fonts on my test systems, Linux seems to have the smallest gap (align the text higher), OSX in the middle, and Windows has the biggest gap (aligns the text lower)

That's a great find, it seems like that looks a lot better than what we have now but we can't crop strings properly. I hate XUL, especially in combination with text and overflow :(

I don't think we can achieve anything better with XUL so we have to optimize for the default case.
