Note that it is likely that the Release version will refuse to use the ESR profile and will create a new release profile and best is to leave it that way and use a xxxxxxxx.default-release profile and copy selected files from the ESR profile to the release profile or possibly use Sync.


You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

In Mac OS X v10.7 and later, the "~/Library" folder in the Home directory is a hidden folder.
