I downloaded Firefox and got his message "The operation can’t be completed because some items had to be skipped..." So what do I do now?

I have used Firefox for years, and am very happy with it overall. When I get the messages that the newest version is available to download, I click on the prompt but the update doesn't work; just sits there trying and trying. So, I go to the Firefox website and download the latest version, and when I try to install it I get this message: "The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again." This message doesn't make sense to me ... and so I'm stuck.

Hello AKBOB, if exist a problem with update or permissions then the better way is to download and install the new version.

1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html

2. Trash the current Firefox application to do a clean install.

3. Install the version that you have downloaded.


Do not select to remove your personal data, your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks or other personal data.

Ideato...

Thanks, that solved the problem. 'Trashing' the old version must have done the trick!
