I have installed Ubuntu 10.04 on my desktop. I have successfully connected my BSNL broadband and can access internet. I have upgraded to Firefox 8. The problem is some webpages are not opening in firefox. Pages like - yahoo.com, flickr.com, ubuntu forum pages etc and lots others are not opening but loading infinitely.
I have also installed google chrome. But same thing is happening there also. My modem is configured in bridge mode. I have disabled IPv6 in firefox. Please help.
