Since latest Firefox 29.0.1 update, I noticed my hard drive space was losing 1-2gb/day. I ran the CCleaner and found out that since the date Firefox has accumulated ~18gb of cached files in the C:\Users\user\AppData\Local\Mozilla\Firefox\Profiles\zm2ibzxb.default\cache2\entries. I have since removed those files. Prior to this, my "Cached Web Content" was set to allow automatic management in the Advance > Network setting. If I check the "Override" feature and limit the cache size to 350mb, some of the webpages load up very slowly even if the current cache size is nowhere near the 350mb limit, i.e. it's currently reading ~50mb. Is there a solution to this where I can get decent performance with automatic cache management but limiting the file max file size at the same time? What's causing such drastic change in latest update? Using Windows 7 Home edition.
