Summary: Amazon page load is slower in Firefox than Chrome → Amazon page load's Time to First Paint is slower in Firefox than Chrome
Here is the correct procedure for profiling: * Load https://www.amazon.com/ * Wait for the page to finish loading * Type "Lord of the rings" in the search box * Time first-nonblank paint * Record when the first non-sponsored result is painted in the correct position with its image Note that I expect it could be important to do this from the amazon UI and not as a bare pageload, because of unload scripts, GC and whatever else. I don't recognize the data from comment 0. Here's the data I have for the amazon search page (all means): Chrome firstpaint: 18.25 frames/304ms Chrome hero: 51.75 frames/862.5ms Firefox firstpaint: 35 frames/583ms (~90% worse) Firefox hero: 60.75 frames/1013ms (~20% worse) This data has fairly large variance and was done against live sites, which is why I hadn't yet filed this bug report, although even with the variance we show a significant different in firstpaint.
