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

hello, thanks for reporting this. can you try to replicate this behaviour when you launch firefox in safe mode once?
Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
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)
which addons do you have installed?
the firefox update to version 60.0.1 that just got released should fix this problem.
I'm using version 63.0.1 on Windows 10 and when viewing facebook page my processor usage goes to 100% usage.
