Thanks for all your replies i was using IE because of that issue and it was damn slow to open this sites. Today my problem is resolved. Actually it was the problem with my proxy and it was given a proxy. When i removed the proxy, it started loading & running websites. Thanks for all your answers and those both links were very useful.

You need to take care to use separate profiles when using multiple versions of Firefox.

We will need more information about your problem but mean while maybe this general information will help. Besides telling us about any error messages please also say exactly what you have tried; to fix the problem, and whether you now have multiple Firefox profiles set up.
