Assalamualaikum I installed Ubuntu 14.04 32 bit several months ago. But I faced a problem from the time of installation. The problem is lots of websites is not opening. Wesites like: coursera.com, edx.com, addons.mozilla.org, prothomalojobs.com and many more important other websites. But all these websites are working perfectly in windows 7. I don't know what is the real problem. This kind of problem didn't exist while I was using Ubuntu 12.04. Also the add on pages of mozilla firefox is blank. But in windows I can see the add ons and install them easily. For better understanding I am attaching an image.
Please give me some suggestion for solving this problem. Regards Sazzad Riyadh
