How to setup proxy settings in firefox?

I’ve installed firefox as user not admin and its installed at the location /user/user-name/appdata/local. Hence its not able to import the proxy setting from my IE and not able to connect to the internet. I dont the default proxy setting of IE too. Now how can I connect to internet through firefox?

Assuming you’re using the most up to date version of Firefox:

1. Click on the orange Firefox button in the top left and then hover over the Options button.
2. On the menu that appears click Options.
3. Go to the Advanced tab and then select Network.
4. Then on the Connection section, click Settings.
5. Configure your proxy settings and then click Okay, followed by Okay.
