The same thing happened to me so this is what i did:
1. open google chrome and click the wrench
2. go all the way down to view background pages, click it
3. a small windows opens and then you click on funmoods or fun dial extension
4. at the bottom, a new button will appear that says end process, click it!
5. you would then get a sign saying the the extension crashed, that means you have removed it from google chrome and the normal background pages you used to have will appear again!
-hope it helps!
