Status: RESOLVED DUPLICATE of bug 1772168

(Firefox :: Screenshots, defect)

Description

Attachment: Take Screenshot of sample PDF in Dark Mode

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

Use Take Screenshot tool on PDF in Firefox when in Dark theme

Actual results:

The document window goes completely black, so that the user cannot see what area is being selected for the screenshot.

Expected results:

Dimming the document window should still leave sufficient contrast for the non-selected and selected areas to be visible when using the Take Screenshot tool.

Hi,

I was able to reproduce the issue with this PDF on Windows 10 and MacOS 11.6 using Firefox Beta 102.0b2.

However, the issue does not occur on Firefox 101 or Firefox Nightly 103.0a1, so it appears to have been already fixed on Firefox Nightly.
Could you please also confirm this? You can download Firefox Nightly from here.

Thank you for reporting!

I confirm the issue seems resolved for me with today's Nightly.

Attachment: Affecting HTML pages when in Dark Mode too

Apologies, I thought this was just affecting PDF pages but it appears to be affecting everything when in Dark Mode, at least on my MacOS.
