Update: This addon no longer exists. Use some other alternative now.
WhatsApp Desktop is a free Firefox add-on which lets you access WhatsApp in a pop-up window. One of the best uses of this plugin is that you don’t need to keep open a tab for using web version of WhatsApp while using your Firefox browser. You can click on its add-on icon to open the pop-up window and chat with your friends.
Apart from this, it also provides the feature to show desktop notifications for new messages. So, whenever someone messages you, a pop-up notification will appear and then you can open the pop-up window to reply to that message.
It also comes with a feature to display the total number of unread messages on its add-on icon, but this feature didn’t work for me. Still, this is a worthy Firefox plugin when you have to access WhatsApp Web on Firefox browser.
In the above screenshot, you can see its pop-up window which lets you open your WhatsApp account to chat with people.
