Should be in Help > About Firefox.
The Firefox 9.0 update isn't currently available for Mac OSX.
You can manually check for & apply updates such as upgrading to the latest version.
1. On the menu bar click the Firefox menu and select About Firefox.
2. The About Firefox window will open and Firefox will begin checking for updates. If updates are available, they will begin downloading automatically. If Firefox is already up to date, just close the About Firefox window.
3. When the updates are downloaded and ready to be installed, click Apply Update. Firefox will be restarted and the updates will be installed.

The Firefox 9.0 update is actually available for Mac OSX.
