The rmannoy extension aims to disable some of the more irksome features of the
Mozilla Firefox browser, such as autocomplete popups and the immutability of
the Bookmarks Toolbar folder.  All options are turned off by default and may
be enabled in the extension's options window.

SUMMARY OF OPTIONS

rmannoy.autocomplete.urlbar
   Disable the location bar popup

rmannoy.autocomplete.forms
   Disable the autocomplete popup for HTML textbox inputs.

rmannoy.autocomplete.searchbar
   Disable the autocomplete popup for the search toolbar widget.

   Note that the form and searchbar autocomplete options overlap with an
   existing firefox option: browser.formfill.enable.  This option, accessible
   through the preferences window as "Save information I enter in forms and
   the Search Bar," is overridden by rmannoy, which offers a greater degree of
   granularity.

rmannoy.autocomplete.all
   Disable all autocomplete popups, regardless of context.  If this option is
   selected, the values of the other rmannoy.autocomplete preferences are
   ignored.

rmannoy.browsermessage
   Disable the message that is displayed at the top of the browser window to
   notify the user of blocked popup windows, missing plugins and extension
   installation attempts from unpermitted sites.  Note that when the
   preference xpinstall.whitelist.required, accessible as "Warn me when web
   sites try to install extensions or theme," is set to true, installation of
   extensions and themes from unallowed sites will silently fail.

rmannoy.password_complete
   Force password saving ability for all sites.  This overrides the use of
   'autocomplete="off"' used by some sites, especially banks.

rmannoy.meta_refresh.enable
   Enable the checks to disable the automatically refreshing the webpage.

rmannoy.meta_refresh.actions
   One of "allow" or "deny", whether to allow or deny refreshes from pages
   matching the exceptions list.

rmannoy.meta_refresh.exceptions
   A space separated list of sites to either allow or deny refreshes, using *
   as a wildcard.
