Dark mode no longer stays active

I normally have Dark Mode always enabled.

This week it's constantly switching to "Follow Device Theme" which then makes it the Light theme.

Interestingly, my phone's theme is also set to Dark mode so the Follow setting doesn't appear to work.

Thanks!

Looks like it's part of: https://github.com/mozilla-mobile/fenix/issues/23104

Turns out it's not a bug, just a confusing feature whereby tapping the FF logo changes the app's theme.

Hi

Is this happening when you are charging the device?

Does this also happen in the Release copy of Firefox for Android (as you appear to be using Beta or Nightly)?

Hi Seburo,

It happens when the charger isn't connected. I'm yet to test it with the charger connected.

I've just installed the RC version and it doesn't appear to happen.

Might just be a Nightly issue.

Hi

Okay, thank you for that information.

Please appreciate that the Nightly version of Firefox for Android may have unresolved issues. I recommend that you report this one at:

Using dark mode does not change out of dark mode when using follow device theme on my s10. Have to go into phone an hit light mode then back to my custom setting to reset for next time. My phone custom works, but follow phone doesn't work in Firefox

Thank you
