How to REALLY clear cache for development

Hi there,

I am a PHP developer and new to SugarCRM.

I have activated the Developer mode in the Admin panel + forced to empty my Firefox browser cache at pages reloading but still I cannot directly see the changes I am doing when reloading a page and mots of the time I have to reload the page several times to see the changes I did, which is very very annoying.

Is there a way to really get rid of this cache for development at each page reloading?

Thanks!
