Firefox problem, Cannot open a website
Hello,
I am a student, I have a DSL connection at home. Sometimes when our professor decides, He will let us take an online exam at CISCO. I am taking up CCNA 1. Sometimes or most of the times, I am using Firefox to visit CISCO web site. Sometimes also when I use Firefox, there is a problem opening the CISCO site, I have to refresh and refresh again, sometimes this solution but most of the time does not. How can I fix this problem. Most of the time, if Firefox can not open a site, I use Google chrome and then Google chrome opens the site. I don't quite like Google chrome because it is not user friendly. please help me,
