In Chrome and IE header slider works excellent but in Firefox I see one problem all of my Sydney Pro Theme websites. After scrolling down, you can see a white space between header slider and the next row!
I have tried change the pictures high (e.g. 1920x1080, 1920x1200, etc.), but didn’t works.
The rows speed doesn’t work.
Firefox Quantum 65.0.1 (64 bit)
