Why doesn't the block up box stay checked? Every time I open Mozilla I have to check the Block pop-up windows.

When I open Mozilla, if I go to Tools, Options, Content, the Block pop-up windows box is unchecked. I have to physically select to block pop ups every time I open Mozilla. I thought blocking pop ups was an automatic default of the system. Has anyone experienced this before?

I wouldn't doubt that McAfee has placed an entry in your user.js file that is turning off the Firefox Pop-up Blocker everytime Firefox is opened.
