Hello julia_cohen

If there is an issue with update or permissions the better, quickest and safest way is to download and install firefox:

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.

Note that you may already have the latest Firefox 16.0.2 version installed.

You can check that via the Firefox menu and select About Firefox
