On Mac you can find the Firefox Profile Folder here:

• /Users/<user>/Library/Application Support/Firefox/Profiles/<profile>/

I'm not sure if this is a hidden folder with the drive connected as slave.

In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.

Open Finder and use one of these:

• Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
• Open the "Go" menu and hold down the Option key to make the Library appear

Thank you for help. Now I have another question - how can i see hidden folder?

You can read that in the second part of my above post.

I found /Users/<user>/Library/Application Support/Firefox/Profiles/<profile>/ . There are a lot of files, witch of them will be bookmarks?

Sorry, thank you sooooo much! Everything is ok =))))
