Ok, Odoo is installed and running fine on a web server.  

With my Google Chrome:

Currently I can go to ip:8069 and view the odoo backend where I have sales, purchases, inventory, website, websiteAdmin, etc. I can see the website at (ip:8069/page/homepage) I guess because Im logged into the odoo app database/selector.

With my Firefox:

But when I try to see ip:8069/page/homepage from my firefox browser where Im not logged into odoo, i get 404 Not Found!

My friends can see the website at ip:8069/page/homepage.
