firefox frame construction and layout measurements

measurements.txt

Pages were opened and refreshed a few times to let the cache settle down before measuring.

"fc" is time spent in the frame constructor NOT including any style resolution that the frame constructor did.
fc-style is the amount of time the frame constructor spent resolving styles; i.e. fc + fc-style is the total amount of time spent
in the frame constructor. fc is the number that indicates potential wins from speeding up the frame constructor
