Reduced address bar contrast using macOS system theme for v126.0

[aphedges]

Describe the bug

When using "System theme — auto" on macOS, as of Firefox v126.0, the address bar is #ECECEC while the surrounding area is #EFEFEF, which is only 3 bits lighter.

Expected behavior

When not using a custom style, the address bar is #F0F0F4 while the surrounding area is #F9F9FB, a full 9 bits of difference. The same amount of contrast is available when using this repo's custom style with Firefox's "Light" theme.

Additional context

All hex values given are for a new profile. I do not understand why, but my existing profile has slightly different colors; however, the amount of contrast between the address bar and the surrounding area are the same regardless of using an existing or a new profile.

I was too busy to check the issue at the time. This looks like the same issue as #897 , so we'll handle it in #897 .
