Name            Firefox
Version         55.0a1
Build ID        20170519030205
Update Channel  nightly
User Agent      Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
OS              Windows_NT 6.1

Also to Note:
This Window 7 (64bit OS) Laptop is using Microsoft's "Windows Classic" theme.

On 2017-05-17, when I updated my Nightly, my 'Location bar' / 'Url Bar' now had a grey background.  

This looked very like the Screenshoot in
Bug 1365789 "Incorrect background color for URL bar on Linux"

He fixed a typo:

-  --urlbar-background-color: moz-field;
+  --urlbar-background-color: -moz-field;

I had hoped that this would 'fix my issue too'.

Note: Bug 1365789 has been made DUPLICATE of
Bug 1365275 "Location and search bars become transparent on hover with a lightweight theme installed"


On 2017-05-18, when I updated Nightly, this was still not fixed (in my case).

I used Build ID 20170518030213 on a new Profile.

The background is still grey (in both URL Bar and the Search Bar).
Seen on First Run.

See Screenshot "Windows-Nightly-x64-2017-05-18-First-Run-on-New-Profile.png".

I wonder if, in my case the "Windows Classic" theme (from the OS), is a significant factor.

See also Bug 1363122:
"Widgets are not correctly drawn in Windows Classic theme
since asynchronous flush rendering has been enabled"


I have created another new profile.
See Screenshot "Windows-Nightly-x64-2017-05-19-First-Run-on-New-Profile.png".

Still 'grey background'.
Also the identity-box 'looks wrong', has a grey background too.
The font size, used for the URL, is 'back to normal' (fixed in BUG 1365906).

Here is a recent Screenshot (2017-05-17 - from another bug - not my PC)
that 'looks OK to me' (for the background color of the URL and Search).
