URL: https://web.whatsapp.com/
Browser / Version: Firefox 54.0
Operating System: Windows 10
Problem type: Something else - I'll add details below
Steps to Reproduce
WhatsApp Web is slow on Firefox, from simply loading a contact/group chat to just opening a image.
From what I've noticed, the CPU usage is very high while interacting with the UI and the about:performance states that it may currently be slowing down Firefox. Also, Firefox uses a ton of memory after loading the main page (not the intro page, the page with your contacts, after you sync with your smartphone) for about 10 minutes.
Thing is, I don't know why. There's nothing that seems demanding in the page itself, so it could be a bug or lack of compatibility from Firefox part.
This doesn't happen on Chrome.
