"Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
There is also security software (firewalls) that can cause such issues, so you may need to look there as well.
