Hi there, You've found a bug in version 124! This bug will hopefully be resolved later this week, when version 124.1 releases. You can track the progress of the bug here.

I apologise for any inconvenience this may have caused.

Thanks!

Hi

Since March 15, 50% of users no longer see Night Mode switch from the hamburger menu. We are using this experiment to monitor and evaluate the impact of removing, so it'll be hugely valuable to hear your thoughts on our feedback platform at https://connect.mozilla.org/.

A dark theme that themes both the app and webpages is still part of Firefox for iOS. You can read more about how to turn this on at: https://support.mozilla.org/en-US/kb/change-themes-firefox-ios#w_set-theme-to-light-or-dark

Thank you.

Here's the workaround for anyone who's interested.

Navigate to Menu > Settings > About and tap on "Firefox <version number>" five times. That will open up a hidden Debug section. From there go to Debug > Experiments > iOS - Night Mode and select "control" instead of "treatment-a". That will bring back the "Turn on Night Mode" menu item.

I pulled this from https://support.mozilla.org/en-US/questions/1443105#answer-1644537. Thanks TimmyTango.

No need for any workarounds.

Hello wonderful contributors! I have yet another update regarding Night Mode. The Product Team took our users' feedback to heart regarding their complaints about missing Night Mode. The experiment has ended, and Night Mode should be available again to all users by end of day. Thanks everyone!
