Hi! Many thanks to all of you for your feedback. As I wrote in Bug
1259520, it must have something to do with FVWM conditions that are
triggered everey few seconds by periodic Schedule commands. These
conditions seem to interfere with Firefox versions newer than 12.
This rings a bell.
In my old setup, I have an FvwmButtons module that is updated every 3
seconds via an fvwmperl module. The periodic command it sends to fvwm is
"UpdateGraphs", which happens to be a complex function from my fvwmrc. I
posted this setup back a bit...

Well, according to the manpage, "during execution of complex functions,
fvwm needs to take all input from the mouse pointer". Such that in
periodically running this complex function, the mouse pointer is being
grabbed every 3 seconds. And if I happen to have a firefox menu open,
then it suddenly disappears. It is as if firefox wants the mouse pointer
for its menu, but fvwm has grabbed it instead?
So I have been mucking around with this. When I rewrote my fvwmperl
module to replace the complex function UpdateGraphs with simpler fvwm
commands, the interrupted firefox menus problem just disappeared. For me
at least.
