1183204 - colours do not show in colour picker in windows 7 high contrast mode

Status: RESOLVED DUPLICATE of bug 1047595

(Firefox :: Settings UI, defect)

Description

[tim]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150630154324

Steps to reproduce:

in firefox select tools-options-content
turn on high contrast mode in  windows 7 (left_alt + left_shift + print_screen)
in firefox select colours


Actual results:

 all four colour  boxes show black instead of the current colours. clicking on a colour box and the drop-down colour selector has all colour squares in black.


Expected results:

each colour box should show the selected colour, and the colour selector should show a different colour in each square in the grid.

Note: actual colours selected show correctly in browser pages in high contrast mode. IT is the colour selection screen where only black is visible.

This makes the colour selector useless for the partially sighted users, who are the ones most likely to use this setting.
turning off high contrast mode restores the correct behaviour of the colour selectors.
