When prompted, drag the Firefox icon into the image of your Applications folder. Doesn't happen; what next?
Trying to upgrade to latest version of Firefox as recommended. Have downloaded file as directed. Then nothing happens. Tried to add troubleshooter and got: "Troubleshooter 1.1a could not be installed because it is not compatible with Firefox 3.6."

How to download and install Firefox on Mac download and install the latest version of Firefox.
If there are problems with updating or with the permissions then best is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox application and save the disk image file to the desktop
- Firefox 31.0: https://www.mozilla.org/en-US/firefox/all.html
- Trash the current Firefox application (open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean (re)install
- Install the new version that you have downloaded

Your personal data is stored elsewhere in the Firefox profile folder, so you won't lose your bookmarks and other personal data when you uninstall and (re)install Firefox.
