Mouse freeze 2sec when opening a new tab or opening FF
When I middle click on a link to open it in a new tab, my mouse cursor freeze (feels like the whole computer) for 1 or 2 seconds.
Also, I noticed, when FF is close and I open it, it also freeze for 1 or 2 seconds.
My install is kinda vanilla. Added UBlock and Lastpass only.

Could be the computer CPU is overworked.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

OK I tried everything in there.
Looks like a CPU problem. But I am running a new Dell laptop with 16GB and an i7-7700HQ.
Start your Computer in safe mode with network support. Then start Firefox. Try Safe websites. Is the problem still there?

Same issue.
It is also hapening with Chrome but not Edge.
I also changed the SSD to an Nvme and completely reinstalled Windows.
