A bug in Firefox 20 causes all loaded jobs to have the HTML < > tags replaced with < and > respectively.
This leads to jobs loading with what appears to be HTML source in the RackForms and FormBoss editors. This may also affect custom PHP code.
Download this file for RackForms (or this one for FormBoss 2), unzip, and replace the existing file of your installation at:
\rackforms\app\js\xml2json.js
This new file will work around the FireFox 20 bug and render HTML items properly.
Please note if you have any forms that have been saved with this improper behavior, this patch should automatically restore the forms to proper working order when you load them into the editor.
