Firefox not connecting internet in 10.04

Are you using a proxy ? If not, please check in Firefox settings if there would be proxy settings entered. If there are, remove them.
I don't know why you would have a proxy set, but worth checking, right ?

No i dont use a proxy it is a direct connection.In firefox is use sysem proxy settings is set. I can use my im and chat software but not firefox 3.6.3

Could you install another webbrowser to see if you have the same problem? You can install Epiphany from the Software Center. Or Chrome from Google website. This way we will know if it's specific to Firefox or not.

I guess you need to decide whether you're using a proxy or not.

Firefox.
Try the option 'No proxy' and test the behaviour.

Verify if you enabled proxy in
system preferences -> network proxy
Enable 'direct connection'.

epiphany is connecting net. but still firefox is not . i even tried no proxy .

Now you know it's Firefox then... But I don't know where to look at, maybe a Firefox specialist can help ? Or you should maybe consider Google Chrome, very impressive broswer also ;)

when i installed epiphany the following error message came.
it also told some of my applications are broken. how to rectify
E: /var/cache/apt/archives/gvfs-backends_1.6.1-0ubuntu1build1_i386.deb: corrupted filesystem tarfile - corrupted package archive
what must i do for the above message

To clean this cache, I think you can do this in a terminal:
"sudo apt-get clean"

Thanks Sam, that solved my question.
