With the latest update of Firefox, my laptop, which is a high end DELL, is experiencing big difficulties just running a Firefox with 3 tabs open. the CPU usage is skyrocketing and it is also heavy on the memory. I am running the same 3 tab on the same websites as I have been doing for the past 6 months, but since the latest Firefox update, this has become impossible. What happened to Firefox? I have had no other significant updates but the Firefox update.

The first article may get you started. An add-on may not work so well with the last browser update, so troubleshoot if need be.
