I've just checked on https://www.mozilla.org/en-US/firefox/releases/ , but 
all that I see are security fixes.  That means I'm either looking at the 
wrong webpage, or the bugfix has not been backported.

... the last version that will run on XP (and ESR to boot), and it has such 
a game-changing bug.  Oh well.

Thanks for the help.
