Recently after the upgrade to Firefox 58.0 I noticed a display bug in my Foundation 6.x orbit sliders. First thought it was a bug in my code, I checked the Foundation 6.4 documentation on Zurb website and noticed that the bug was also present. The problem is that when a slide move on the left to make appear the new one, it first show a blank area, then the picture. So, at this moment, all my websites using Foundation 6.x orbit slider stopped working correctly. It seems that previous versions of Foundation are not concerned.
Here is an animated gif of the issue (youtube links make my posts marked as spam):
I quickly made some tests with several versions of Firefox and here are the results:
FF 57.0 -> no bug
FF 58.0b3 (first beta) -> bug
FF 58.0 -> bug
So, is it a bug in Firefox or a problem in Foundation orbit which is revealed by this release of Firefox ?
I could also post this on Firefox website, but I think that the audience would be less sensible to it than here.
Any suggestions or ideas about this issue ?
