Old MacBook crashed. Water damage. Only Hard Drive salvageable. Cannot use finder>Go>Library>App Support.Firefox IF I am searching the external Old Hard Drive. Desperately need instructions on how to get Firefox data from external hard drive. I am attaching an image below of my OLD HARD DRIVE view. The top image is what I see if I select the "User Folder". There is no Library, there is no Application Support. The bottom image is what I see if I select "Library". The folder is empty. You can see that I have been a Firefox user for three years now. I love Firefox! I just need my data and Bookmarks badly :( Maybe it helps to know that when I bought the new Mac at Apple Store they did a data transfer of the Applications ONLY.
