Did you check the Age of the Entries by using about:cache?device=disk?

I can still reproduce this with the latest nightly. Mozilla/5.0 (Windows NT 6.1; rv:7.0a1) Gecko/20110624 Firefox/7.0a1

I can confirm seeing this on 16.0.2 release for Mac... Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0

Any update on this? My Internet connection is very slow and expensive so I used large cache storage for better web surfing. Yesterday my friend used my laptop to check his mail. I cleared all the data during last hour and closed browser. After starting it again, I've noticed things loading much slower and from about:cache saw all disk caches are cleared out.. I'm sure it contained +100MB last week that I checked it to diagnose a web designing problem. And Today i reproduced same problem.. On Firefox 18, Gentoo linux build.

I can confirm that it still happens for me with Firefox 20.0 on Mac.
