<p>Since upgrading to the glass bed my prints are failing right after the point where I finally feel confident that they are adhered well and printing smoothly.

Once the filament sticks it does it doesn't have any gaps or thin spots. If those tails from the beginning of the print snag on the extruder as it passes over that area again it will pull them up but if it doesn't the new layers all lay down smoothly and don't seem to have gaps or get the nozzle dragging through the filament.

basically you either have a discrepancy in where the top of the part should be vs where it is or an issue with the part curling and detaching due to thermal issues.  check bed leveling, verify the bed moves how much it thinks it moves via calipers, and check the filament diameter vs your programmed settings.  Also try to print a bit cooler; you need to find the sweet spot that is hot enough to stick but not so hot that the part curls a lot when it cools.

Sounds like either a leveling problem or a greasing glass bed... Can you share a photo of the underside of the prints?
