Why can't I update Firefox on my Mac?

Every time I try to update Firefox (for months now), it doesn't work. I download the dmg file on my Mac and then I can't get it to work. Today I tried 47.0.1 and then a window pops up saying "The following disk images couldn't be opened." It lists the file (under the heading "Image"), Firefox 47.0.1.dmg and then says, "Reason: not recognized." Anyone know how to fix this?

Hello, please try one more time to download a full copy of firefox and then install that copy, follow the next steps:

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.


thank you
