Heat oven to 350°F. Line a 9x13-inch pan with parchment, leaving overhang for lifting.
Combine graham crumbs, salt, and melted butter. Mix until evenly moistened.
Press the mixture firmly into the pan to form an even crust.
Stir vanilla into the condensed milk, then drizzle it evenly over the crust.
Scatter chocolate chips and butterscotch chips evenly over the surface.
Sprinkle on coconut and pecans. Press lightly so layers adhere.
Bake until edges are deep golden and center looks set, 22–26 minutes.
Cool completely in the pan. Lift out by parchment and cut into bars.
