830445 - Webpage animation regression in https://www.fitbit.com/zip

Status: RESOLVED FIXED

(Tech Evangelism Graveyard :: English US, defect)

Description

[Jared Wein [:jaws] (please needinfo? me)]

This is the pushlog that I found with mozregression, http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=bf26f61a0748&tochange=84320dffec6e

Last good 2012-12-22
First bad 2012-12-23

The center part of the webpage is supposed to animate horizontally. Starting with the 12-23 build the animation no longer occurs and there is no horizontal slider.

Hey Jet, this feels layout related. Do any of the bugs in that range appear to be related? If not, we can try to get a more granular regression window.

moving to 'all' platforms since this is happening on Mac too.

The site is using optimizely:
<script src="http://cdn.optimizely.com/js/76742810.js"></script>

your regression range matches the first regression range from me in in bug 825473.

Please make sure to track all optimizely bugs in bug 824301 (depending on it) and bug 821606 (blocking it).

Apparently related to optimizely.com scripts, though I'm not sure how sites opt in to their server-side fixes.
