Sun Cult

Worldwide Sunrise, Sunset, Twilight Times and Moon Phase Calculator as a Mozilla Extension.

One can also view Moon Rise, Moon Set, Sun and Moon Azimuths, Date of Next Full and/or New Moons.

The Sun Cult icon shows a brief overview of the current situation and the mouse over pop-up displays the more detailed information. The location of the icon can be placed in any toolbar.

All items for display can be configured on or off to suit your interests.

It also supports a Calendar mode to view the Sun and Moon properties on any date.

Supports versions up to at least Firefox 42.*, Thunderbird 10.*, SeaMonkey 2.* & Firefox Mobile.

Note that with the introduction of plugin signing in Firefox, installation of the plugin should be through the standard Add-On Manager search within Firefox (i.e. automatically using https://addons.mozilla.org).

Otherwise installation of the XPI downloaded from SourceForge may not work as currently this plugin is not signed.
