We have CKFinder (version 2.4.1) integrated into CKEditor (version 4.3.1) and while it works fine in IE8-10 and Chrome, the "Browse Server" button as well as all other CKFinder functionality is missing when using FireFox. In looking at the source it appears the button and functionality is being hidden but if I use developer tools to unhide these the "Browse Server" button does not do anything.
Any ideas?
P.S. Tried the CKFinder demo and it works there in both IE10 and FireFox. I'm not seeing anything in the Browser Console that is of any help.
