Firefox + Popups

[Modeps]

For some reason every once in a while, the "Block Popup Windows" checkmark gets unchecked in my Firefox. Thus allowing a bevy of stupid ad windows to popup (without ads in them due to adbloc) Anyone else have that problem?

wtf it just happened again... is there some javascript that will disable it?

Is it happening at a specific website?

It's possible there's some new spyware that removes that option, why not makes your prefs.js file read-only and see what happens?
