963083 - Background tabs should inherit the text color

Status: RESOLVED FIXED

(Firefox :: Theme, defect)

Description

[Dão Gottwald [::dao]]

Since background tabs are transparent, it makes sense for them to just inherit the text color rather than having it set explicitly to the right value. On Windows and Linux, we already set the right text colors (e.g. CaptionText, -moz-menubartext) on #TabsToolbar.

This made non-LWT tabs have white text on OS X inherited from the global skin. See the screenshot to follow.

AFAICT, this would be a change in behaviour for Aero Glass and Win8 because CaptionText isn't set on #TabsToolbar for -moz-windows-compositor. Are you sure we want to do this?

Yes, the color for that text was supposed to be set here: http://hg.mozilla.org/mozilla-central/annotate/f550b112a19b/browser/themes/windows/browser-aero.css#l132

OK, if you're sure this is what the UI team wants, then it's fine with me. If you're unsure, please check with them.

It doesn't even matter practically, as CaptionText is just black with the compositor enabled...

This broke text-shadow on selected tabs on OSX without lwthemes - they now have a dark text shadow, which looks awful. Backing out 124eee46ccb6 locally fixes it.

attachment 8364489 [details] already showed this. I meant to fix this in the latest revision of my patch here, but somehow missed it. Filed bug 968442.

Comment 13

[:Gijs (he/him)]

Should this + bug 968442 be uplifted or are we OK leaving this as-is for Aurora? I'm not sure if this fixed any actual user-experienced bugs or just made the CSS more straightforward.

Comment 14

[Dão Gottwald [::dao]]

This is just cleanup. Uplifting it might make sense to reduce the risk of differences between aurora and central affecting other uplifted patches.

Ah, right. Perhaps, what with the win8 styling and all the other 'tweaking' we're still doing, we should consider doing that... Would you mind putting up a combined patch and requesting approval? Thanks!
