RESOLVED DUPLICATE of bug 1736218

People

(Reporter: hecerinc, Unassigned)

Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

Since Firefox 96 or so (presumably related to this change: https://twitter.com/MorgynRae/status/1461490677238276097), sites have started to read my system theme (I'm actually not sure if it's my system or firefox theme), and enabling dark mode when they support it (e.g. Google, YouTube). While I like dark mode in my FF theme, and OS, I do not particularly care for browsing sites in dark mode (unless I specify it via their own cookies).

I've been looking for a setting to disable this behaviour in FF but have not found it yet. Is this possible yet? Otherwise is this something that you could consider adding?

Actual results:

Sites read my system theme and I have to change them all manually. Using containers make this a pain, because this has to be done over and over again.

Expected results:

Having a setting to prevent sites from reading system theme (or alternatively, forcing light or dark theme by default)

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.
