Determining the Installed Version

You can find out what version of Firefox or Thunderbird you have installed on you computer by opening up the application and choosing:

• "Help > About Mozilla [application]" from the menu bar on Windows
• "Firefox > About [application]" from the menu bar on Mac OS X

where [application] is either "Firefox" or "Thunderbird".

Updating Mozilla Firefox (Windows & Mac)

1. To manually check for a Firefox update, click the "Help" menu on the menu bar, and select "Check for Updates..."

   • On occasion, you may see "Apply Downloaded Update now...", rather than "Check for Updates..." -- the same process applies.
2. If there are updates available, click the "Get the New Version" or "Update Firefox" button
   • If no updates are available, click "OK" or "Done" to close the window.
3. When the install process is complete, you must restart Firefox. To close Firefox and re-open it, click "Restart Firefox".
4. Finally, verify that there are no more updates to be installed by performing Step #1 again. Depending on what version you start with, Firefox may need to run through this process multiple times.
