[Plugin: Frontpage-Slideshow] Strange issue with Mozilla Browsers and J Shortcodes plugin

There’s and strange issue that only happens with mozilla based browsers (I’ve tested with Firefox and SeaMonkey) in combination of the wordpress plugin “J Shortcodes” v 1.302 (https://www.ads-software.com/extend/plugins/j-shortcodes/):

When one activates j-shortcodes the text buttons in Frontpage-Slideshow, in the frontend disappear. They still shows in the backend.

I’ve test this issue also with MS-IE, Opera and Safari and there’s no problem with those browsers, just with Mozilla based ones.
