On our site (malice.dkpsystem.com) the "Browse" button to upload images to the gallery is greyed out in FireFox but works in Chrome. Did Mozilla make some weird change that caused this and is there a fix?
It's an unfortunate hack from a time before being able to select multiple elements was properly built into the browser. It hasn't been changed yet because "don't fix what ain't broke". But I knew the time would come that I'd have to rewrite it.
