Description of problem:
Firefox sets itself up wrong as the default gnome web browser. First I
set Firefox up to be the default web browser using Preferences->More
Preferences->Preferred Applications. If I then launch firefox directly
or have it launched by evolution from a link, two things to note.
First, it prompts that it's not the default web browser, would you
like to make it the default. Note I just said I set it to be the
default in the preferences. Selecting yes causes it to set itself up
wrong as the default gnome browser. A quick check of about:plugins
shows all system installed plugins available. Note this is the same
initial invocation. Now quit firefox and launch it via a link in
evolution. Check about:plugins and see none (or at least no system
wide plugins that hang out in /usr/lib/mozilla/plugins.) Now quit and
launch it again from the menu or a launcher and the system wide
plugins are there. So however firefox sets itself up as the preffered
gnome web browser makes it not search system directories for plugins.
