Steps to reproduce:

Actual results:

When the container moved, all of the images disappeared during the transiton.


Expected results:

All of the images in the container should have slid with the container during the transition.

Please provide testcase

See http://jsfiddle.net/w58G3/1/, and click on the button at the bottom right, and notice how the images disappear.

On further investigation, it appears that this only happens when I include the style for .icon-share.highlight, even though in the sample, that style is never actually used (It is in my actual website).

I can't reproduce, the slider works fine to me, Ubuntu 13.04, Firefox 29.0.1.

Please check if the issue occurs using Firefox in safe mode (with your addons disabled):

And on a new, empty profile:

I can reproduce in safe mode and with a new profile. However, when I first load the jsfiddle, it works fine, it only happens after I click "Run" at least once. I have no idea why that would make a difference.

Also, if it helps at all I am using Ubuntu 12.04 with the GNOME shell.

This is a strange Linux specific issue.
I see it now in FF 29, 30, 31, but seems to be fixed in the latest nightly 32.
Give it a try: http://nightly.mozilla.org/

Comment 7

Yes, it appears to be working in the nightly build.

Comment 8

[Paul Silaghi, QA [:pauly]]

So, you can use Nightly for now, until it gets to release in couple of months.

Based on Comment 6 and Comment 7 I will mark this as Resolved Worksforme. Reporter fell free to reopen it if you still have the issue on latest Firefox versions (e.g. Firefox 43).
