My next step in debugging was to rename the ~/.config directory when 
logged out of KDE plasma, and then logging in and starting iceweasel.

That ran fine, so I reverted the ~/.config directory and moved the 16 
most recently modified files and directories under it out the way, and 
again logged into KDE plasma and started iceweasel, leading to a lock-up.

I then moved the next 16 most recently modified files and directories 
under ~/.config out the way and logged into KDE plasma and started 
iceweasel successfully.

That would suggest that one or more of the second group of 16 of files 
and directories under ~/.config were responsible for the lock-up.

However, after several cycles of logging out of of the KDE plasma 
desktop, moving the files and directories back a few at a time, and 
logging back in again, at no stage did I experience another lock-up.

I did find that kwin was not using the Plastik style that I had 
previously, (and some other window behaviours were also different from 
how I had set them) so I changed them under "Window Manager Settings" 
and was again able to log out of KDE plasma and back in again and run 
iceweasel without problems.

It appears that there was some configuration that kwin_x11 was reading 
that had lead to the lock-up on loading iceweasel, but I have no way of 
finding what that was now.

Is there any documentation on what configuration file(s) kwin_x11 uses?

If I had known specifically where to find settings and move them out the 
way for testing purposes, I could have saved some time in isolating the 
problem.
