I have Firefox 10.02. I have few years of experience with HTML, CSS, PHP and have never had such a problem before. I am changing CSS, for example, header height from 100px to 50px. Uploading style.css to my host. Refreshing page in firefox does not display changes. I close firefox open again - no changes. When I analyze element with firebug it shows that height still is 100px and not 50px. I restarting my PC and opening firefox and still no changes. I opening IETester and I can see changes, but not in firefox. In setting for clearing history I have "when closing firefox automatically clear all" and cache check box is marked. In Advance, network, I click Clear now and have cache 0 bytes in disk space. Nothing helps. Only next day I open firefox and see changes.
What else I have to change to see changes right away? Please advise.
