Some little time ago, I became unable to initiate a technical support chat on centurylink, my ISP. I have since become able to using IE, but still not on firefox. The "Start Chat" buttons on the centurylink contact page simply do not appear when using firefox. I have since excepted pop-up blocking on centurylink.com and centurylink.net on firefox to no avail. On-Off status of AdBlock Ultimate has no effect on this. Not long ago, I was perfectly able to initiate chats on centurylink using firefox, so something has changed. I have cleared the cache, the history, the cookies, everything I can think of. Is there a solution to this issue?
