What Browser Do You Use?

My browser of choice is Firefox 53.0.3 64 bit. I stayed with the older version because all my plugins still work (even after Firefox's recent dust-up with killing plugins). For those sites I can't get to with FF, I use in this order: Edge, Chrome, Opera, I.E. I used to use PaleMoon but that one started messing with my plug ins so I switched back to FF.
