Firefox for iOS Removes Night Mode, Triggers User Outcry

Firefox for iOS version 124 stripped the night‑mode setting from half its users in a gray‑scale data‑gathering test, prompting fierce backlash from light‑sensitive users, while the three‑engineer team blamed a deteriorated codebase for the month‑long effort and pledged a full refactor by year‑end despite Apple’s restrictive iOS ecosystem.

Firefox for iOS Removes Night Mode, Triggers User Outcry

Firefox for iOS version 124 removed the “night mode” option from settings for 50% of users as a gray‑scale test to collect data.

The change sparked strong criticism, especially from users with light‑sensitivity conditions who rely on a true dark mode for accessibility.

The iOS Firefox team, consisting of only three engineers, said the codebase has deteriorated over years of neglect, making even small changes like adding a button require a month of refactoring.

They aim to complete a full refactor by the end of the year, but Apple’s closed ecosystem continues to limit what Firefox can offer on iOS.
