Hi,

I'm just back from the home page on Firefox but don't see any anomaly ? What is jumping ?

Hi,
i think he means the issue i mentioned here:

look at my screencast:

Hi,
Yes as shaolinsteyr1 said it seems to be caused by the carousel. The whole homepage jumps/pulls almost 1cm to the left in firefox for me everytime the carousel slide/content changes. Its very noticeable from the top of the page for me, and if I scroll down, can see that it occurs everytime there is a new testomonial. Appears to work fine in Chrome, Shame as looks a great theme. Hopefully something you can replicate and fix.

This happen on Firefox for Windows only. It's hard for me to test because i've only Browserstack.com and it's a bit slow to keep all details.
I've created a pen, can you tell me if firefox jump on this ?http://codepen.io/myconcretelab/pen/VeMeyz...

Hi,
This happens also on linux, but on your link, there is no jumping at my firefox on linux.

I'm experiencing the same. On each short moment when slides are changing a second scrollbar appears left from the default one.

Since using Firefox on Windows is not too exotic, it should be easy to reproduce and explore. ;)
