I have been playing around with some css3 transitions and created a slider test. It works perfectly in webkit browsers, but I have noticed an issue in Firefox 4. When clicking on the left link for the first time, the slider is supposed to slide to the left, but there is no css transition until the second click. I have posted the demo on jsfiddle - http://jsfiddle.net/mrleroylee/ctY68/
Could this be due to something in my code or is it a bug?
