We have generated our Webhelp projects from RoboHelp 11. These display fine in Firefox on Windows. However, when viewing them on a Mac OS X version 10.9.2 with Firefox 28, an unresponsive script warning is encountered which cannot be resolved. Also, there is a lot of padding in the Index between the text field and the index entry. Screenshots are provided to show both of these issues.
When viewed on Safari on the same Mac machine the Webhelp project is simply unresponsive.
Is this a known issue with Mac OS X?
