Hi, I've been using the Family Safety software suite included with Microsoft Essentials for filtering/blocking purposes with the computer of a child I tutor. Recently, as in only the last couple of days, the "Block Everything" or whatever it is called stopped functioning; I can see that he has been on a ton of websites that I definitely did not add to the allowed list. I've worked with parental control software before, so the first thing I looked for was plugins that might be having a negative effect on the software; nothing.

The browser being used is Mozilla Firefox, updated to the latest version. The OS is Windows 7 Professional 64-bit.

Any help would be greatly appreciate; without the parental controls my student will not be allowed to use his computer on the internet without supervision, and his mother cannot devote that kind of time to watching him.

Thanks so much!

PS: Family Safety isn't an option in the Products list when posting this, so I put it where I thought the second best place was.
