How can I remove Firefox using terminal?

I'm a beginner with Mac OS X. Would somebody please tell me how to fully uninstall Firefox using Terminal on Mac OS X Lion?

I'm experiencing hangs and crashes with Firefox 5.0.1, so I want to remove it then re-install it.

Thanks so much in advance.

Solution 1:

To remove Firefox.app:

• Login with an administrator account
• sudo rm -rf /Applications/Firefox.app/

You get the same result by just dragging the Firefox app from /Applications/ to the trash.

If the crashes continue after reinstalling, deleting preferences and support files in the user library may help:

• ~/Library/Preferences/org.mozilla.firefox*
• ~/Library/Application Support/Firefox
• ~/Library/Application Support/Mozilla
• ~/Library/Mozilla
• ~/Library/Caches/Firefox

Solution 2:

It's very probable that your profile is corrupt, rather than Firefox itself (in which case, deleting Firefox won't help as any new installation will use the corrupt profile).

Creating a new profile may help - the safest way to do that is using the Profile Manager.
