After the latest microsoft upgrade to explorer firefox will not open unless I click "following program to make changes." The program is Mozilla. Then firefox opens, but the message to make changes appears again afterwards each time I want to open firefox.

Chosen solution

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties". Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

  • Privilege Level: "Run this program as Administrator" should not be selected
  • "Run this program in compatibility mode for:" should not be selected

Also check the Properties of the firefox.exe program in the Firefox program directory.

The compatability mode on my pc is Windows XP service pack 2. I am using Vista I assume serv. pack 2. Should I change XP to Vista?
