For those who do online gold trading (like me), I made a tiny gold price watcher extension for Firefox, which displays current gold price (and the change) and USD to RMB exchange rate (useful to me ;-))
The data is retrieved from Kitco.com and Bank of China and is refreshed every 3 minutes. Single clicking the status bar area will refresh the data. Double clicking will display the chart.
Click here to install it. If you have problem installing it directly, please right click the link and download the xpi file and drag-n-drop the file into your Firefox to get it installed.
