Can you not see what is happening by carefully examining the log file (log/development.log)? For example if two requests were being made you should see that there. Another thought, have you validated the full page html in the w3c html validator? Differences between browsers is often a sign of malformed html. Also check in the firebug plugin in firefox that there are no javascript errors.
