High CPU/RAM Usage with Facebook FF 58
Since Thursday, when I open Facebook, my CPU and RAM usage immediately spike and, in less than 100 seconds, CPU usage hits 100% and stays there while, within 3 minutes, RAM usage hits >5GB.
All this is with no other applications running, and only one tab open.
No other websites give me this problem, nor does it occur with Edge or Chrome.
I have uninstalled and re-installed FF58 twice, but still have the same problem.
At this point in time, I am forced to use a different browser as the problem with the combination of Facebook and FF58 is too severe to allow me to use FF.
Please advise.
