For about the last 5 days I am not able to use Google Search on my MacBook Air using Firefox. My start page is Earthlink. I keep getting this error message ( Application error ; a client side-exception has. occurred ( see the browser console for more information ). My email is [edited] @earthlink.net. Could the problem be Earthlink or Firefox. I am also unable to use Ebay, but when I switch to Chrome I can do both.
