Up till now, I've been able to update Firefox effortlessly. With the 50.0.1 update, my Mac (OS10.11.6) won't let the download finish. It sends a message : download failed due to lack of permission. I've turned off my antivirus software. Doesn't help. Also when I open Firefox 49.0.2 a Firefox icon pops up on my desktop Never happened before.

Hello redressler1, please try the next steps, download and install firefox:

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

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.
