I start the FvwmDebug from the desktop menu. I guess it invokes "FvwmDebug
-xc".

I am using Fedora Core 2. The problem may be system-related. But I believe
there must be some hiding bugs in the request handling codes of Fvwm. I
just found another problem which may not be related to this Firefox issue:
when returning from the "acroread" fullscreen mode, the window cannot be
moved.

Anyway, this is a development version.

Best
