I was checking the Firefox preferences and I noticed that on the UPDATE tab under Advanced I have checked Automatically check for updates to: "Installed Add-ons" and "Search Engines" but where it says "When updates to Firefox are found:" It is grey out. (it doesn't let me select anything). Do you guys know what the problem might be? I tried disabling the firewall and nothing. Please let me know. My Firefox is not doing automatic updates.
