Facebook extremely slow on Firefox after latest update

Just noticed this today, and it seems to be only happening on the Facebook home page. I'll be trying to send a message to someone in the mini messenger pop-up on the bottom, and everything just goes SUPER SLOW. I'll type out a whole paragraph and the message is still being typed out letter by letter by the time I'm already finished typing. I can't switch tabs while this is happening, otherwise the whole message disappears and the page reloads. I also checked Task Manager (Windows 10 64-bit) and the Firefox process has 6 processes running, all at 10% CPU usage, and over 2GB of memory dedicated to it. Once I change tabs away from FB, the CPU usage drops dramatically to less than 5% total

The problem doesn't appear to be happening in Firefox in Safe Mode. Not sure which add-on would be causing the issue though, since this only started happening once Firefox updated to the latest version (Earlier this afternoon)
