No problem, it may happen, even in the best of families!  ;-)

I don't think it should save anything to the configuration file, if I
haven't changed any setting at all! In other words, the configuration
file should stay absolutely untouched, unless I actually changed
something.

And anyway, it should not mark settings as manually-changed, if I
haven't changed them manually. I thought this was obvious...

Moreover, it should not set some options to non-default values (such as
audio-lang, for instance), if I haven't done anything to them.

Finally, I didn't hit OK, as there is no OK button.
There is only a Close button, which is another thing that I strongly
dislike in some "modern-looking" configuration dialog windows: there's
no OK/Cancel choice, only a Close button that's supposed to be used to
exit and it doesn't allow me to change my mind and avoid saving the
configuration!

So, no, sorry, I disagree: I think that the configuration dialog is
*not* working as expected.

$ iceweasel

$ LD_DEBUG=libs LD_DEBUG_OUTPUT=/tmp/ld_debug_iceweasel.out iceweasel

Awkward, it mentions nothing about plugins.
Did I do anything the wrong way?

I honestly do not know...

Thanks again for all the time you are spending on this issue.
