Transfer Firefox settings, logins, and bookmarks from a semi broken PC.
Can you tell me how to copy and transfer firefox settings, logins, and bookmarks from a P.C. that will not run via the O.S. ( Windows 7 ) I am wanting to copy from, but the hard drive is intact and accessible via an older O.S. ( Windows Vista ). I would like to transfer the FF stuff via copy to flash drive to temporarily transfer to a Windows 8.1 OS. The Win7 and Win Vista are installed on two seperate hard drives, and Vista still works and accesses the Win 7 Hard drive. Not sure about some kind of security or access allowed messages I get though.

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 (Root directory).
