in safari & chrome my application cache initiates a new download only when the manifest file has been update (as expected). In FF5.0 it initiates the download on EVERY page load. When I view the data @ ''about:cache > Offline cache device > List Cache Entries'' I notice all of the pages listed are "0 bytes" in size, while the CSS/JS/images are given correct size data... Is this a bug or has anyone dealt with this issue before?
