About this extension
WhatsApp Web is handy cause it doesn't sign out from the existing device. But on mobile, we can't access it. This extension helps with that. It uses the existing WhatsApp Web, spoofs as a PC, and customizes it to get a better preview on mobile.

Directions:
On Android (via Firefox browser)
1. Install the browser and install this extension.
2. Visit the site "web.whatsapp.com" and sign in.
3. Now the UI should be mobile-friendly.

On iPhone (via Orion browser by Kagi)
1. Install the browser and install this extension.
2. Open Orion, go to Settings -> Privacy ->User Agent -> Custom and paste the below without any quotes
"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:148.0) Gecko/20100101 Firefox/148.0"
3. Visit the site "web.whatsapp.com" and sign in.
4. Now the UI should be mobile-friendly.

Note: WhatsApp will redirect to "web.whatsapp.com/mobile" if the "Desktop site" or the "User agent" was not changed, so make sure to go back to "web.whatsapp.com" after updating.
