Have you done ping tests and traceroutes to make sure its the browser that is causing your problems?

yep i did ping tests especially to www.google.com and it works.when i update my fedora core via yum i can download all the updates from internet.so it shows that i have internet connection.and also i can open www.gnome.org and some of websites.i really cant understand what is happening?

Do you have DNS servers set in your configuration?

actually all my internet connection settings was done by fedora and it was configured by dhcp.it means it took all settings from automatically from my d-link adsl modem.

by the way when i try to connect my msn and yahoo messengers via gaim it doesnt connect.however my kopete works very well.now i am thinking that gnome 2.14 for x64 have a lot of problems?

That is very strange...I really dont even know where to go from there. Seems like it would be a browser problem, but with you reinstalling it that should have been taken care of. Sorry I can't help more but maybe someone else that is a bit more familiar with firefox can be of assistance.
