Having currency exchange rates displayed in your web browser can be useful in several situations. Maybe you prefer to buy some goods overseas and want the exchange rate right in your browser to make a rough product price calculation. Or you are trading on the foreign exchange market and want to make sure that you have the latest currency exchange rates displayed at all times in the browser. It can also be handy if you are planning your next out-of-country trip and need to convert currencies to get a better feeling for prices in the other country.

The Firefox add-on Dcurrency displays exchange rates of up to three currencies or metals in the Firefox status bar. It will automatically display three different currencies in the status bar upon installation. Each currency can be swapped for another one with a right-click.

The first currency on display is the reference currency which is always listed with a value of 1. The two remaining currencies or metals are then displayed with their exchange rate.

The program can display rates for six metals: Aluminium, Copper, Gold, Palladium, Platnium and Silver. These are displayed in the same fashion as currencies.

Yahoo Finance is used by the extension by default, with options to switch to Google Finance instead if that's the preferred service. Rates are updated once every 15 minutes, with options to reduce the interval to one minute. It is however possible to update the exchange rate directly with a left-click.

One handy tool is the converter mode which you can enable in the extension options. This replaces the value of the reference currency with a form to enable currency conversions right in the Firefox status bar.

The add-on can display exchange rate graphs which visualize exchange rates over time.

Especially the option to look up exchange rates right from the status bar can be useful for Firefox users who sometimes need to make those currency conversions.

Firefox users can download and install Dcurrency from the official Mozilla Firefox add-ons repository.
