Huge browser window icons in TWM

A recent update means that all my browser window icons are a quarter-screen tall, and some are wider than my nice big new monitor - the biggest is 2058x276 pixels !

I have had this problem before; at one level the problem is that I use an ancient window manager - twm.
I had a solution - https://support.mozilla.org/questions/950850#answer-428414 - overriding the default association between WM_CLASS and icon in my ~/.tmwrc but now the icons have lost their WM_CLASS.

Turns out my association for firefox was case-incorrect and something has stopped doing caseless matches. My first thoughts are recent security updates to libxml and expat. Anyway, spelling firefox in lower case has returned the icons to my sensible size.

Get Out Of Jail Expensive

Thinking about how I would feel if I was released from prison at a cost of £400 million and a war*.

Like Helen of Troy ?

Like the dad in Iron Eagle (a Top Gun rival where a military brat causes an international incident when he borrows a jet fighter and rescues his dad from a middle east military jail) ?

I think that much weight on my shoulder might be a bit of a downer, at least for a decade or so, until I shook it off.
