Affected versions

• Fx89.0a1 2021-04-08

Affected platforms

• Windows 10 64-bit
• OSX 11.2.3

Preconditions

• The following prefs are enabled in about:config:
  browser.proton.enabled
  browser.proton.toolbar.enabled
  browser.proton.urlbar.enabled

Steps to reproduce

1. Launch Firefox and from about:addons - Themes, select Dark Theme
2. Input a long string in the address bar and then select around half of the string using the mouse or the keyboard
3. Change the theme to Light and repeat the previous step

Expected result

• The selected string matches Figma dark and light themes

Actual result

• For dark theme: Text selection is white (Windows) and blue-ish (OSX) if the window is in focus, respectively grey when the window is out of focus
• For light theme: Text selection is blue

Regression range

• Not a regression, text selection is the same pre-Proton

In the dark theme spec, there's a note that says text selection color should be determined by the OS, meaning the current behaviour is correct. I think other parts of the Figma spec using a different highlight color is a mistake in the spec. Amy can confirm.

Marking as P5 since this seems to be a need for Figma adjustments

I believe this is a duplicate https://bugzilla.mozilla.org/show_bug.cgi?id=1476524

Hi, yes this is determined by the OS.

But the white highlight in dark theme should be fixed so please take a look at 1476524, it looks wrong and bad
