Easy Slide does not work,

Updating to the new version does not fix this issue, per the other support topics indicating that there is a massive gap between browsers. For example, Avia_Slider aka easy slider, only works on one version of chrome, and not on firefox or safari. Updating does NOT solve this issue alone. The update itself is lacking vital code for cross browser compatibility, and this is in relation to the theme short codes which are native to the theme. Please advise.
