I Am on desktop:

i5 9600KF (high performance mode) 16GB 3200mhz ram NVME... Windows 10 Pro x64 Firefox last stable

When I open Firefox tabs aren't loaded all at the same time, but they are suspended. So after that: when I switch between 6 tabs quickly - they start to open at the same time. And CPU usage skyrockets to 100% LOL! Given I Am on high end PC - this is joke! I was using chrome and had hundreds of tabs and Chrome doesn't even suspend them by default. They open all at the same time I think!

So there is something wrong! I tried troubleshooting mode and it was the same problem!

Thanks for help!
