Hello, I have a strange problem, so after loading the system, the processor in my computer is drastically loaded, after entering the task manager, it turns out that one firefox process uses a lot of processor (photo in the attachment) after closing this process everything returns to normal and CPU consumption even while browsing the internet does not exceed 7% but it is quite persistent because I have to close this process every time, I will just add that this problem does not occur in other browsers. and none of my friends have it either. I'm using Windows 10 with the latest updates and the latest Firefox developer edition. The problem has been around for about a year and is really bothersome. My processor up to i7 2760qm, I have 16gb of ram. I will also add that in my second laptop with core 2 duo, this also happens only with me, no one who has this problem. Thank you in advance for your help.
