Scan the QR code to open WhatsApp Web on your desktop. Click your profile picture or contact name in the top bar and choose Settings from the dropdown menu.
Activate Dark Mode in WhatsApp Web
In the Settings panel, look for the Appearance or Theme option. Toggle Dark mode on, and the interface of WhatsApp Web will switch immediately to a darker color scheme.
Enable Dark Mode in Mozilla Firefox
Set Firefox Theme to Dark
Open Firefox and go to Settings > General. Choose Dark from the Themes section so that the browser interface respects dark mode.
Connect WhatsApp Web in Firefox
Visit web.whatsapp.com in Firefox and scan the QR code with your phone, just as you would in Chrome.
Turn On Dark Mode for WhatsApp Web
Once WhatsApp Web loads, tap the three dots or your profile icon, then Settings, and finally Appearance. Enable Dark mode to confirm the switch.
Managing Appearance and Notifications
Switching Between Light and Dark
If you prefer different themes at different times, return to the Appearance settings in WhatsApp Web and toggle between Light and Dark as needed.

WhatsApp Web usually remembers your last selection. If it does not match your system theme, adjust the browser or WhatsApp Web settings to align them.

FAQ
Reader questions
Why does WhatsApp Web stay in light mode even after I enable dark mode on my system?
WhatsApp Web may not detect changes until you manually select Dark mode in its Appearance settings or refresh the page after switching your system theme.
Can I use dark mode on WhatsApp Web if my browser does not support it?
Most modern browsers support dark mode, but if yours does not, you can still enable dark mode directly in WhatsApp Web's Appearance settings independently of the browser.
Will enabling dark mode affect my notifications or message delivery?
No, dark mode only changes the visual appearance of WhatsApp Web and does not impact notifications, message delivery, or account functionality.
Does dark mode save battery on my computer or phone?
On OLED screens, dark mode can reduce power consumption, but on standard LCD displays, the savings are minimal and do not significantly affect battery life.
