STR: 1. View a message that Thunderbird thinks is a scam, in Thunderbird Aurora (v43) ACTUAL RESULTS: The scam warning is unreadable (white on light yellow). See attached screenshot. EXPECTED RESULTS: Readable text. NOTE: The "blocked remote content" notification uses a different text-color and is consistent with what I'd expect from using OS-dependent theming, based on bug 1198063. I'm using Ubuntu 15.10 prerelease (currently beta, releasing this month) and Earlybird 43.0a2 (2015-09-28) (thunderbird aurora channel)
For comparison, here's the more-readable other notification, which is rendering as expected per bug 1206516.
I'm guessing we use a special text-color on the scam notification, with the intention of being extra-visible -- but in this case it means we're extra-invisible. :-/

(Also: I noticed that I need to tick a checkbox before the scam notifications will show up -- there's a checkbox in the Thunderbird Preferences "Security" pane.)
Requesting tracking, since this is a regression which effectively disables a security feature by rendering its warning unreadable.
This is a toolkit issue. The color is set here: https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/linux/global/notification.css?offset=200#20 . With the corresponding background-image it would be white on red. But with the -moz-appearance: -moz-gtk-info-bar; set here: https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/linux/global/notification.css?offset=200#10 the background-image isn't used. With setting -moz-appearance: none; like on https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/linux/global/notification.css?offset=200#17 the red would be shown. If you want to go this way I can make a patch.

CC'ing adw, who last touched that line (to fix a similar black-text-on-dark-background bug, bug 1130850). "-moz-appearance:none" does sound like it would work, but it would remove the native look-and-feel which seems unfortunate. Hopefully adw can make a call (or defer to someone who can) about what's the right solution here.
oh, I spoke too soon -- I think I agree that "-moz-appearance: none" is actually the right solution after all. It sounds like this dropdown's background *used* to be drawn (native-looking or not) via the "background" or "background-image" properties, and we were *intentionally* overriding the native background-color in this notification[type="critical"] rule. But now that the native background is drawn via "-moz-appearance" (as a result of bug 1198063's fix), the formerly-overriding "background-image" in this [critical] declaration doesn't end up being visible. So: if I'm understanding correctly, I think I agree with Paenglab that we should add "-moz-appearance:none" to this notification[type="critical"] rule. Hopefully adw can confirm and/or review the patch.
Add the -moz-appearance: none;

(Tree sheriffs generally require a Try build before they'll land checkin-needed patches. But I'm pretty sure this doesn't need a Try build, so I just went ahead and pushed, to bypass that back-and-forth with sheriffs.) This needs backporting to Aurora 43 [which is where I encountered it, in Thunderbird]. Richard, could you request aurora approval?

Note: - version 42 [current beta] is unaffected, because we disabled GTK3 on that branch (bug 1207310). - version 41 [current release] is unaffected, because GTK3 wasn't turned on until trunk hit version 42 (bug 1186003). Plus, the regressing patch -- bug 1187203 -- didn't land until in Firefox 42.
