codeigniter project work only on LAN or wifi connection and not with 3G USB modem

[eluser]fcodebue[/eluser]
I develop a project with CI 1.7 and I'm becoming crazy ...
Infact my project work without problem with
- localhost installation
- web installation (UK)
: LAN ADSL connections
: wifi connections

but when I try tu use Vodafone or 3 3G connection with USB modem I have these kind of problems:
- firefox show only first page after login but doesn't open my customer detail page with 50 fields
- chrome works
- opera works
- IE 9 works

probably it's something around delay from connections and firefox it's more restrictive than other browsers.
I optimize source following google speed suggestions...

How I can solve this?

some idea?

It almost sounds like this is just a internet connection issue. But if you can more details with "firefox show only first page after login but doesn’t open my customer detail page with 50 fields", maybe you can elaborate that more...

naturally your are right...

I have one form to login into the app... naturally np, after this I have a customer list... and here np again...
after link on customer company name CI have to show a customer detail form

but firefox doesn't load it...

If yu wanna I can send you login user/pwd to test (in private)

Post your recent related controller and view, maybe theres more than internet connection issue, since you stated it fails only in FF.
