Hello I have been very stupid. I have a lot of useful Firefox logins, passwords and bookmarks, stored on a computer which now won't boot. The data were not synced to any other device. I can read the C drive using a system rescue disk, and have been able to copy emails and other data to a working computer. Is there any way to copy the Firefox data from the non-working computer and import to Firefox on my working machine? Basically I need to know, in terms of directory and file names, where Firefox stores these data, and any problems in reading these files. The dead computer used Windows 10, version 2004. Firefox used automatic update, so would be the latest version as of last Wednesday. Many thanks for any help. Peter Kenny
