Comment 2 for bug 1478173

Steps to reproduce (sorry for not including these up-front):

 1. Download a "Desktop" firefox nightly build from https://nightly.mozilla.org/

 2. Extract the tarball, e.g.:
  tar jxvf firefox-42.0a1.en-US.linux-x86_64.tar.bz2

3. From inside the extracted directory, create an empty folder and start Firefox Nightly using that folder as your profile:
   cd firefox
   mkdir /tmp/ffprof; ./firefox -profile /tmp/ffprof -no-remote

 4. (Tell the pop-up dialog no, don't make this your default browser.)

 5. Look at the dropdown notification bar at the top of the browser.

ACTUAL RESULTS: ~white text on ~white background, as shown in screenshot here:
