Like most apps, uninstalling Firefox from an Apple computer is a simple matter of deleting the application file. OS X Yosemite doesn't have a complicated uninstall application. However, Firefox does have additional library files that aren't removed when you delete Firefox.app. Locating these files in Finder can be tricky, since they're stored in a hidden library folder, but Firefox's help menu can point you directly to these files.

Step 1

Click the "Menu" and then the "Help" icon.
