Problems with Mozilla Firefox

I'm having trouble with Firefox v3.6.8, whenever I load it up it says:
"The connection was reset" "The connection to the server was reset while the page was loading."
But Chrome and IE both work fine, I've tried uninstalling Firefox, deleted my cookies, clearing my cache etc. and it still won't work.
Anyone know what's wrong with it?

This has happened to me a few times, and i just disconnected my Internet and re-connected it and it works fine.

Just tried that, still isn't working.

Did you setup firefox to try and use a Proxy? That may be causing it.Options -> Advanced -> Network Tab. -> Connection settings.

Nope, no Proxy.
