Background
Disk caching saves copies of the downloaded files on the hard drive so they doesn't need to be downloaded to be redisplayed. These pages can be viewed by anyone with permission to the cache folder. Pages transmitted with SSL encryption often contain sensitive information and caching of these pages to disk may present a privacy risk. This preference controls whether to cache to disk pages that were transmitted with SSL encryption.
Possible values and their effects
true
Cache to disk content retrieved by SSL.
false
Don't cache to disk content retrieved by SSL. (Default)
Caveats
- It is recommended that this preference be left at false to lessen the chance of sensitive information being disclosed to others.
- browser.cache.disk.enable must be set to true if you wish to enable disk caching of SSL pages.
- If this preference is set to false, browser.cache.memory.enable must be set to true if you wish to enable memory caching of SSL pages.
