Try the following:

  1. Open the Mac Task Manager
  2. Stop the Firefox.exe process from the task manager

NOTE: I am not a Mac user and have no experience using Mac computers. The above steps work in Windows and should work in Mac as well, but I am not sure how to open the Task Manager equivalent on Mac.

Hello bobvn, if you have problem with update firefox 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.
