Hi, I've just upgrade my Win10 from 1803, also the video adapter driver was update, FF still at same version 76.0.1 but I've noticed much mre SPU usage especially when I open a new tab and it loads a site, it can go to 100% all cores for some seconds, when it takes too much I need to close FF and the CPU goes to very low levels 2-5%. There is usually a more CPU used even when a page is loaded and without anymations. I believe there is a bug in FF with latest Win10 or latest Intel HD 620 drivers

The problem may be connected to the bad new driver for my Wireless AC 3168 netwtw04.sys, I got 2 times a BSOD adter wake up from st-by. I rolled back of the last year driver, seems better, I'll post here is solved
