Firefox has major lag on new computer when other browsers are super fast.

Hello. I have a brand new computer. Firefox was working great when I first bought it. For the last few days it has a major lag like an old computer with too many viruses. My others browsers are super fast. I've deleted and uploaded Firefox several times. I've hit the reset as I've seen in other recent complaints like this and nothing is working. Please help and thanks!

Please see the reply from philipp in this thread regarding accessibility services, which affect performance on some Windows 10 systems: Firefox 57 hangs up.

God bless you, Sir! Once I hit the prevent the Accessibility Services everything went back to fast. What suddenly caused this problem? Thanks again!

I'm not sure why this is a huge problem, but I imagine it is at the top of the list to be fixed.
