Since refreshing, I cannot reliably move puzzle pieces in jigsaws. They jump when touched by the cursor!
I refreshed Fire Fox earlier today. Then attempted doing online jigsaw puzzles at http://www.jigidi.com/ and a few other sites. When I attempt to drag and drop, the puzzle piece often jumps away from the cursor, or entire puzzle jumps into upper left of screen. When I finally get hold onto the piece, it drags very slowly. I realize it's a javascript problem, but don't know how to correct it without going back to my old version of Fire Fox. Using Windows 10 and Fire Fox 43.0.4
