High CPU usage when signed into Firefox account

Hello,

I recently installed a new CPU cooler which works great, I'm idling at around 37C, but when I use Firefox my temps jumped all the way to 67C and CPU usage was around 12-15% which I though were unusually high. I then decided to sign out of my Firefox account because I know that constantly has to sync data to see if it would lower temps and sure enough that was the problem. Now I'm able to use Firefox and my temps are in the low 40s and the CPU usage is at 0% which is an insane difference. So the purpose of this comment is to let the Firefox team know that I think you guys need to optimize how Firefox syncs data because I'm sure it is causing major stress on other peoples' computers

Désolé je parle français. J'ai exactement le mem e problème, avec un i9 qui est monté à 78 degrés au demarrage de Firefox. Je vais déconnecter et l'utiliser non connecté si c'est cela le problème. Merci pour l'information mohdsameer. Il faudrait que la synchronisation se fasse 1 fois par jour quand Firefox est en avant plan. Pas quand on est sur du multi-àcran avec un jeu ouvert à coté. A reflechir les amis.
