787694 - firefox 15.0 private browsing saves caches

Status: RESOLVED DUPLICATE of bug 787743

(Firefox :: Private Browsing, defect)

Description

[argon.vegell]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0
Build ID: 20120824154833

Steps to reproduce:

I've done a clean install of Firefox 15.0, I went to options, then I went to, "Advanced", clicked on "Network", on my Cached Web History, it says, "Your web content cache is currently 180KB of disk space", then Offline Web Content and User Data says, "Your application cache is currently using 0 bytes of disk space", then I clicked on “Clear Now” on both, now Cached Web History says, “ Your web content cache is currently using 0 bytes of disk space”, and Offline Web Content and User Data has the same message, then Privacy, then set Firefox to "never remember history" then cleared current history by clicked on "clear all current history" then I clicked on Okay.


Actual results:

Then I exited Firefox, then reloaded it, then I did a Google search, then I rechecked Cached Web History, it says “Your web content cache is currently 3.0KB of disk space" and my Offline Web Content and User Data is using 0 bytes of disk space, I also double checked my Privacy settings, it is set to "never remember history".

Here's the results of about:cache after activating private browsing mode, then exiting, relaunching, and then surfing:

Information about the Cache Service

Memory cache device
Number of entries: 50
Maximum storage size: 18432 KiB
Storage in use: 536 KiB
Inactive storage: 536 KiB
List Cache Entries

Disk cache device
Number of entries: 3
Maximum storage size: 256000 KiB
Storage in use: 17 KiB

Offline cache device
Number of entries: 0
Maximum storage size: 512000 KiB
Storage in use: 0 KiB


Expected results:

In private browsing mode, no entries in about:cache should be made. I tried this on the previous version, Firefox 14.0.1, and everything works fine on there, except in Firefox 15.0.

this does not need to be security sensative
