I'm unable to update Firefox. operation can't be completed because you don't have permission to access some of the items. I own the computer, why would I not have permission? This has happened other times and I don't know what it means.

I just wanted to update firefox and it won't let me. I drag the icon into applications, then a window ask me if I want to replace older version. I click yes and the window mentioned above appears. I purchased this computer new, I'm the only owner. Why would I not give myself permission to do something on my own computer.

If you get an error message that you do not have sufficient permissions or have problems with updating then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.

Download a new copy of the Firefox program and save the DMG file to the desktop

  • Trash the current Firefox application to do a clean (re-)install
  • Install the new version that you have downloaded
