Can we please get some attention to this issue?
This is a documented bug in Firefox according to this stackoverflow post:
Here is the Firefox bug documentation:
As bug report is 8 years ago, I don't think Firefox is going to fix it very soon. Please help.
It's unsustainable for our organization to go in and edit the Robohelp generated output each time that it is updated.
What's odd about this thread is that apart from the original post, no one until you has encountered this. If this was a common problem, then the thread would have had a lot more posts.
Also this is essentially a user to user forum where the users are technical authors and this is something that would need developer skills.It's really something for Technical Support.
First though, do you have all the updates applied as I'm wondering if this was fixed in an update and that explains the lack of others posting here?
Check that and if that fails contact Adobe's Technical Support. Let us know how you get on with that and if necessary I will flag the issue with some contacts.
