User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Firefox updated automatically from version 91.0 to 92.0

Actual results:

After Firefox updated to the latest 92.0 version, it could not detect Windows 10 themes or the user's high contrast mode. Dark theme also did not work. Websites would display a white background with dark text rather than a black background with white text. This happened to all websites. Disabling and re-enabling did nothing nor did a fresh re-install of Firefox. I was forced to uninstall Firefox and install version 91.0 in order to use high contrast mode (black background, white text).

Expected results:

After updating to the latest version, Firefox should've been able to detect Windows 10 themes and high contrast mode. It should also have been able to detect it's own dark theme. It should've been able to display websites in a dark background with white text. Unfortunately, it did not do that after the update.

The Bugbug bot thinks this bug should belong to the 'Firefox::Theme' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hallo Mozilla!
Warum ist im Firefox 92 (Windows 10, DarkModus!) mit dem aktivierten Adon Dunkel(!) die Tabseiten(!!) hell ???
Im gegensatz zu Ff.91.02 ! Bin sehbehindert und kann nur mit dem totalen DarkModus arbeiten !

Google translate says:

Hello Mozilla!
Why is the tab pages (!!) light in Firefox 92 (Windows 10, DarkModus!) With the activated Adon dark (!) ???
In contrast to Ff. 91.02! I am visually impaired and can only work with the total dark mode!

I don't think I can help with this question.

I was able to replicate this on windows 10 64bit

Reproduced on Firefox:
92 release
93.b2 beta
94.0a1 nightly

  • Change windows settings to high contrast mode
  • Launch firefox, open a new tab

On Mac 10.15 & Ubuntu 20: If the theme is Dark and high contrast is on, the new tab page looks dark.

Is this just the new tab page, or are other ff pages (I'm think about preferences, addons, etc.) also affected?
Can you post some screenshots of the current behaviour?

Also, does the behaviour change if you toggle the Use System Colors checkbox?

Thanks Pablo, does that behaviour change if you toggle 'use system colors' in the about:preferences colors dialog?

gotcha. EDIT: thanks for the screenshot! :)

:hontonidekai :hans you may want to give this a try if you're experiencing issues. You can navigate to this checkbox by going to:
about:preferences > Language and Appearance > Colors > Use System Colors

Sorry for the confusion, does your experience change if you enable the checkbox? Or are you experiencing an issue that is different from the one Pablo captured in the screenshots?

Clear needinfos that are pending on inactive users.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
