"A web page is slowing down your browser. What would you like to do?"
It only appears in Firefox when opening up facebook.com news feed. Here's what I do: - Open facebook.com as usual - Scroll down the news feed - A warning appears for a few seconds and the page does not respond - Then the warning disappears and the page responds again - Continue Scroll down the news feed - And warnings reappear, and so on
The problem still happens in Safe Mode.
Specification: Windows 7 Ultimate (64 bit) Firefox 63.0.3 (64 bit)
