WebHelp published output does not display the TOC, index, glossary, or search on Mozilla
Firefox version 35.
For Help output that is not previously generated, in the following folder, take a backup of the whutils.js file and copy the extracted whutils.js to this folder:
<RoboHTML10 install directory>\RoboHTML\WebHelp5Ext\template_stock
If you copy the file to the install folder, it's necessary to regenerate the WebHelp. If you copy the file to the generated folder, no further steps are required.
