ActiveX Installation - Firefox 1.0

Step 0. IMPORTANT. If you use the Adblock Extension, you must make sure that the setting for OBJ-TABS is disabled. Otherwise, your system will run almost any ActiveX control. See Note 5.

Step 1. Ensure that you have Windows Media Player 9 or 10 installed. They can be installed through Windows Update.

Step 2. Download Adam Lock's ActiveX Plugin for Firefox 1.0 from here: http://www.iol.ie/~locka/mozilla/plugin.htm#download
Click 'Download the xpi'. DO NOT click 'Click Here'.

Step 3. Install the plugin: Open firefox, then drag the mozactivex-ff-10.xpi file you just downloaded into the Firefox window.
The xpi will install all of the files that make up the plugin into Firefox when you do this.
While installing, the plugin will appear in the Extensions window. Then it will vanish - this is because even though it installs the same way, this is not an extension.

Step 4. When the installation is complete, restart Firefox.

Step 5. Apply this registry patch: http://plugindoc.mozdev.org/resources/wmp9.reg
It solves the problem of Firefox trying to use the WMP 6.4 plugin, instead of the WMP 9/10 one.
To apply this registry patch, download the file to your desktop and then double-click it. A pop-up will ask if you want to add the information in it to the registry - click Yes.

Step 6. You can test the ActiveX installation here: http://www.accuradio.com/#
If the radio loads and plays, ActiveX and a sufficiently recent version of Windows Media Player are installed correctly.
