Aplication's Help cant find iceweasel

[Gary Roach <gary719_list1@verizon.net>]

Hi all,

Running Debian Stretch on KDE Desktop

I recently switched to Firefox-esr and removed iceweasel from my system. 
Some application help files now error out with: KDEInit could not launch 
'/usr/lib/iceweasel/iceweasel. As an example Rosegarden has the problem. 
How can I fix this.
