1187246 - Remove scroll tracking from Mozilla.org home page

Status: RESOLVED FIXED

(www.mozilla.org :: Pages & Content, defect)

Description

[Alex Gibson [:agibson]]

When the 2015 mozilla.org homepage redesign launched, some of the marketing folks we're concerned people would not think to scroll down the spage to view content underneath the full-screen promo area. To get data on this, we added scroll-tracking to the home page when it launched.

The JS required for this tracking to occur weighs in at around 10KB. It may not be all that much, but it's little things that add up to a lot. We've had plenty of time to get enough data on this I think. The inclusion of the tracking doesn't really benefit the user in any meaningful way, other than requiring them to download more JS and also the performance hit of performing the scroll tracking itself.

I'd like to suggest we remove this JS from the home page in our continual effort for performance.

We also have this JS file that was used for a short-term scroll experiment that we can more likely remove:
