- Create a page, and attach a .wmv file.
- Go to this page, click on Insert > Other Macros > Multimedia Macro and add.
- If you're running Firefox, you'll need to install an plugin for Firefox called: wmpfirefoxplugin.exe.
- Once you installed this plugin you'll try to go back to the page and run the file.
- You're going to see that the Confluence will ask again for the plugin, and even if you install again, it doesn't work.
The same occurs for Chrome.
