Change+Your+Thunderbird+Receive+Sound

Are you bored with the standard message alert sound in Mozilla Thunderbird? Would you like to spice things up a little, with your own custom sound? First, open up Thunderbird and click **Tools > Options** up on the toolbar. Ensure **the General tab is selected**, and under the “**When new messages arrives”** heading, click the radio button for “**Use the following sound file”**.  This should enable the Browse button, so you can use your own sound file…  Click **Browse**, then browse to the sound file on your hard drive that you want to use as your new message received alert sound. When you find it, click **Open**. When you are finished you can either click **Play** to test your sound or click **OK** and wait for a new message!
