I lost my bookmarks when I updated - I have a file on my desktop that is labeled old Firefox data. Nothing I can find explains how to get the old data file back into the new version. Some articles do talk about how to restore lost bookmarks but they all assume I can "see" the old files if I click on the restore tab in bookmarks. That will show me the Old Firefox Data folder, but when I open it none of the file folders appear to contain the HTML data needed.

I am 76 years old and not terribly computer literate. I need rudimentary explanations to solve my problem.

Failing that, can I just go back to my old version that worked?

Thanks,

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).
