Firefox 158 – Incorrect Date and Time Field Display in Hebrew (RTL)

Hello Mozilla Support, I'm experiencing an issue with how Firefox displays date and time input fields on websites when using Hebrew (Israel). **Environment:** - Firefox version: 158.0 (64-bit) - Operating system: Windows - Browser interface language: Hebrew - Regional locale: he-IL **The problem:** Date fields are displayed in the format YYYY.MM.DD (for example, 2026.10.14) instead of DD/MM/YYYY (14/10/2026). Time fields also sometimes display their components in an incorrect order, apparently due to right-to-left (RTL) handling. This issue occurs across multiple websites, including the standard HTML date input example on MDN, so it is not specific to any particular website. **Troubleshooting already performed:** 1. Verified Windows regional settings: Hebrew (Israel), short date format dd/MM/yyyy, and time format HH:mm. 2. Verified Firefox regional preferences show he-IL. 3. Tested intl.regional_prefs.use_os_locales with both true and false. 4. Tested intl.locale.requested with he,en-US, he-IL,en-US, and he-IL. 5. Changed the preferred website language order to prioritize he-IL. 6. Restarted Firefox after making changes. Unfortunately, the date issue persists, and the time field display is also inconsistent. **Expected behavior:** Date fields should display DD/MM/YYYY, and time fields should display HH:mm in the correct visual order, while keeping the Firefox interface in Hebrew. Could you please confirm whether this is a known Firefox bug and whether there is a supported workaround or a planned fix? Thank you.
