The Tor browser dark theme is available now in c/firefox@lemmy.ml
[–] goestav@lemmy.world 3 points 2 months ago

It’s the default (as in default selected theme) for desktop. I’m not sure if that’s the case for Android, I unfortunately don’t own an Android phone currently to check.

The prefers-color-scheme being reported as light seems to be coming from Firefox’s resist fingerprinting feature (which is always enabled on Tor browser).

This website always reports light for me as well, same goes for manually checking with JavaScript. I think that value gets spoofed regardless of the enabled theme.

For me it’s dark mode by default. 🤔 I use MacOS but I think it should be the same on all operating systems.

In a previous post I asked what your thoughts were on the theme I was working on and it immediately became apparent that users were wondering how this would affect their anonymity.

From my research on the matter I found that this should generally not be a concern. I recommend you read my detailed explanation which can be found in the readme of the source code.

The theme is originally designed for the Tor browser, but I made an extra effort to make it work on Firefox as well. You can install it from the add-ons store if you'd like to check it out. 😄

I addressed how this affects fingerprinting in this comment.

The short answer would be probably not. Tor browser uses dark mode by default, and since this is also a dark (mode) theme that doesn’t change. It only affects the chrome of the browser, not the pages themselves.

The longer answer is that in theory it may be possible to use some kind of exploit or side-channel attack to figure out what theme is enabled or which themes are available through media queries for example with JavaScript or CSS.

So that is something you should keep in mind for your threat model.

My answer is based on personal experience, some basic googling and asking the Tor community. But it still can’t hurt to do some additional research yourself. 😄

Feel free to correct me if I’m wrong.
