If you are using Firefox as your default browser and your icons appear like blank pages it means you have an error on your registry.
To fix it:
1. Press your Windows key + R
2. Type regedit
3. Look for HKEY_LOCAL_MACHINE\SOFTWARE\Classes\FirefoxHTML
4. Delete the ShellEx registry key.
5. Close Regedit
6. Restart computer.
The icons should appear normal now.
QUESTION: How do I make Chrome, Firefox, Opera or Safari open links when using other applications such as Yahoo! Messenger?
By default Windows will use Internet Explorer, to change this you need to make a change in your default programs.
Before you begin you need to have the browser already installed
Now when you open the links from other programs it will immediately open your selected browser, to change this follow the instructions again.
