I compile nightly from a local hg repository with my own
configuration.  I am using gtk3 and I saw this scrolling behavior
before implementing the workaround. I was also using nightly as my
default browser instead of the fedora version, but several addons don't
work with nightly.  In particular, the maff save page add on seems to
work, but doesn't save the page.  I believe this is due to the new
sandbox feature in firefox.  Addons that affect content will have to be
rewritten to use frame scripts, to separate control from manipulation.
Apparently, this sandbox feature, which is to enhance security, will be
in the production versions by the end of this year.  At that point, I
expect all the addons will upgrade to the new style, and will fail on
older versions of firefox that don't support the feature.

For now, they still work properly on the fedora version.

I *think* the behavior was a compromise in gtk3 / gtk+ in order to allow
touch screens and pointers to both work with the same code.  But that
is just a guess.
