Yesterday when I was using firefox 15 to retrieve my emails, I found the header words & some body words in the emails (like subject, date, & some words in the text body) were highlighted. As I moved the cursor to those hi-lite words, spam/virus pop-ups appeared - like you can make $xxx per month, a young girl face with enticing message, etc. At first, I thought my firefox 15 was corrupted. I upgraded to firefox 17, and the same phenomenon is happening still. I then had a live chat with earthlink.net tech support last night, thinking it was earthlink problem (see below). He saw the pop-ups on his screen also and suggested that I used IE to access my emails, which did not have those "surprised" pop-ups. Thus, he concluded that the problem is with firefox browser. Since Mozilla/firefox do not have live chat. I need to resort to send you this email. My question is: Is my firefox browser very corrupted that I need to stop using it, and to delete everything related to mozilla/firefox in drive c?
