Parental Controls: Destroys Firefox Cookies

Question

After turning on parental controls, and after adding specific sites to "always allow" Firefox was thereafter unable to use any cookies. I tried everything (deleting the cookies, rebooting, reinstalling Firefox, etc.). The same problem was not occurring in Safari, so it seems to be Firefox-specific.
After I disabled the parental controls, the problem persisted.
After I deleted the parental control profile for the account, the problem went away and Firefox works normally now.
I therefore conclude that Parental Controls have two issues:
1 Disabling content filters is not as thorough as deleting the parental control profile.
2 Parental controls have a negative impact on cookie use in Firefox.

Answer 1

Thank you for your reply.
In addition to the above, I believe it is a major error to disallow access to any and all secure sites (https://). Yes, the data is encrypted and can't be scanned and filtered, but that's an arbitrary elimination of half the Internet with a setting that's buried in the software.
There should be a little checkbox in the parental controls that says:
*[ ] Allow secure sites (https)*
Most sites start with a non-secure page and then take the user to a secure site. The filter should review that initial page, then give the go-ahead for the secure portions.
Apple must remember that the purpose of an Internet filter is to remove all the garbage, not control people's computing lives. I reluctantly return to Intego (http://intego.com) for a solution.
