My Macbook Pro is running 10.7.5 I got an update notice in Firefox and tried to update to v. 17.
I. When I try to move the download to the Applications folder:
(1) If I choose "Replace," I get the error message: "The operation can’t be completed because you don’t have permission to access some of the items."
(2) If I choose "Keep Both Files," I get the error message: "The operation can’t be completed because an unexpected error occurred (error code 0)."
II. Version 16 no longer works:
1. If I try to open it now, I get the error message: "You can't open the application Firefox.app because it may be damaged or incomplete."
2. If I try to throw out the damaged app, I get the error message: "The operation can’t be completed because the item “Firefox.app” is locked."
Can someone help me with this? Thanks!
